The Code That Built the Donor Class

The Code That Was Designed

The Sixteenth Amendment to the United States Constitution, ratified February 3, 1913, authorized Congress to “lay and collect taxes on incomes, from whatever source derived, without apportionment among the several States, and without regard to any census or enumeration.”¹ The amendment’s ratification, after a sixteen-year political process that began with the 1894 income tax act struck down by the Supreme Court in Pollock v. Farmers’ Loan & Trust Co., was the constitutional foundation of every subsequent federal income tax statute.² The Revenue Act of 1913, signed by President Wilson on October 3 of the same year, established the operative form of the federal income tax: a graduated structure with a basic rate of one percent on incomes above three thousand dollars (approximately ninety-six thousand dollars in 2025 dollars) and a top marginal rate of seven percent on incomes above five hundred thousand dollars (approximately fifteen million in 2025 dollars).³ The structure affected, in its initial form, approximately three percent of American households. The remaining ninety-seven percent paid no federal income tax. The federal revenue stream the structure supplied was modest in absolute scale and was supplemented by tariff revenues, excise taxes, and the new federal estate tax that the Revenue Act of 1916 would establish.⁴

The estate tax established by the 1916 Act was, in retrospect, the more structurally consequential of the two innovations. The Act imposed a graduated tax on estates above fifty thousand dollars (approximately one and a half million in 2025 dollars) at rates rising from one percent to ten percent for the largest estates, and was framed in the contemporaneous political debate as a structural response to the inheritance-driven wealth concentration that the late nineteenth-century industrial expansion had produced.⁵ Theodore Roosevelt, in his 1907 message to Congress that opened “The Donor Class” essay in this series, had specifically called for “a graduated inheritance tax on big fortunes, properly safeguarded against evasion, and increasing rapidly in amount with the size of the estate.”⁶ The 1916 Act was the operational realization of Roosevelt’s call. The structural argument behind it — that unconstrained intergenerational wealth transmission produces concentration that representative government cannot survive — was the same argument that had animated the Tillman Act and that would animate every subsequent component of the post-Progressive American tax framework. The estate tax was the principal instrument through which the framework intended to constrain dynastic wealth.

The framework that emerged across the 1913-1944 period was, in operational terms, a system designed to constrain the highest-income and highest-wealth American households through high marginal rates, while leaving the great majority of American households outside the federal income tax system entirely. The top marginal rate on individual income rose to fifteen percent in 1916, to sixty-seven percent in 1917, to seventy-seven percent in 1918, fell to twenty-five percent across the 1925-1931 period, and rose again under the Roosevelt administration to seventy-nine percent in 1936, eighty-one percent in 1940, and ninety-four percent in 1944.⁷ The estate tax top rate followed a similar trajectory, reaching seventy-seven percent under the 1941 amendments. The structural intent of the framework was not principally to raise revenue from the constrained population — the population was small enough that even at high marginal rates the revenue contribution was modest — but to constrain the magnitude of the concentration the framework was operating against. The framework, in this respect, was an explicitly anti-oligarchic instrument. Its specific provisions, including the high marginal rates that contemporary commentary frequently treats as historical anomaly, were the operative form of the constraint.

The Eisenhower-era top marginal rate of ninety-one percent, which has become the standard contemporary citation in the comparative-tax-policy literature, was the operational continuation of the 1944 framework across the postwar period.⁸ The rate, which applied to individual income above approximately four hundred thousand dollars (approximately four point five million in 2025 dollars), was effective on a small population — fewer than ten thousand American households fell into the relevant bracket — and produced modest absolute revenue. The rate’s structural significance was the constraint on top-end accumulation that the rate effectively imposed: at a marginal rate of ninety-one percent, additional pre-tax income above the threshold produced approximately nine cents of additional after-tax income for the affected taxpayer. The structural incentive to accumulate income above the threshold was, in effect, eliminated. The structural mechanism by which the highest-income American households of the post-war period were prevented from accumulating wealth at the rates the contemporary period has produced was the high marginal rate operating on the income that would otherwise have funded the accumulation.

The framework’s other structural features — the corporate income tax (which approached fifty-two percent across the 1950s), the estate tax (with top rates of seventy-seven percent), the progressive structure of individual income taxation — operated as components of the same anti-concentration system. Capital gains, throughout most of this period, were taxed at preferential rates compared to ordinary income, but the differential was narrower than the post-1981 period would establish, and the highest-income population was nonetheless constrained by the high ordinary-income rates that applied to the substantial portion of their income that was not in capital-gains form. The system’s overall effect, viewable in the income-distribution data, was the substantial compression of the post-tax income distribution that defined the post-war American economy. The top one percent of American households held approximately eight to ten percent of national income in the post-war period; the same percentile holds approximately twenty percent in the contemporary period.⁹ The compression was not a market outcome; it was a policy outcome, produced by the operation of the framework that the 1913-1944 sequence of statutes had constructed and that the post-war Congresses of both parties maintained.

The Inversion

The 1981 Economic Recovery Tax Act, signed by President Reagan on August 13 of that year, is the foundational statute of the contemporary American tax framework and the structural inversion of the framework the previous section described.¹⁰ The Act reduced the top marginal rate on individual income from seventy percent to fifty percent, indexed the rate brackets to inflation (a substantial structural change that prevented the bracket-creep mechanism by which inflation had progressively raised effective rates across the 1970s), accelerated capital cost recovery for business investment, and expanded the categories of pre-tax savings vehicles. The Act’s headline reduction of the top marginal rate was the most-cited single feature; the structural reorganization of the corporate and capital-gains treatment was the more consequential.

The 1986 Tax Reform Act, the bipartisan reform commonly credited as the most substantial overhaul of the American tax code since 1913, completed the inversion that the 1981 Act had begun.¹¹ The 1986 Act reduced the top marginal rate further to twenty-eight percent (from the fifty percent the 1981 Act had established), eliminated a substantial number of deductions and tax shelters in exchange for the rate reduction, equalized the top capital-gains rate with the top ordinary-income rate at twenty-eight percent, and lowered the corporate rate from forty-six to thirty-four percent. The Act was passed by a Democratic-controlled House (under Speaker Tip O’Neill) and a Republican-controlled Senate (under Majority Leader Bob Dole), with substantial bipartisan support, on the framework that lower marginal rates with broader bases would produce equivalent revenue with less distortion. The framework was the operating reform-economics consensus of the period; the empirical evidence subsequent to enactment has, as the section below describes, substantially complicated it.

The structural feature of the 1981-1986 inversion that the subsequent decades have demonstrated to be most consequential was the equalization of the top capital-gains rate with the top ordinary-income rate. The equalization, which had been the long-standing position of tax-policy reformers across both parties, was the structural mechanism that made the lower marginal rates politically defensible: the wealthy were taxed at a lower nominal rate, but they were taxed at the same rate on every category of income, eliminating the differential that had previously allowed high-income households to convert ordinary income into capital-gains income through tax-planning structures. The equalization lasted approximately five years. The 1990 Omnibus Budget Reconciliation Act and the 1993 Omnibus Budget Reconciliation Act re-introduced the differential, with the top capital-gains rate set at twenty-eight percent while the top ordinary-income rate was raised to thirty-one percent (1990) and thirty-nine point six percent (1993).¹² The 1997 Taxpayer Relief Act under President Clinton further widened the differential, reducing the top capital-gains rate to twenty percent while leaving the top ordinary-income rate at thirty-nine point six percent.¹³ The 2003 Jobs and Growth Tax Relief Reconciliation Act under President Bush extended the preferential treatment to qualified dividends, taxing them at the same fifteen percent rate as capital gains while ordinary income remained at thirty-five percent at the top.¹⁴ The differential between the two rates was, by 2003, approximately twenty percentage points — the largest in the history of the federal income tax — and has remained at approximately that level through 2025.

The structural consequence of the differential is the principal structural feature of the contemporary American tax framework that distinguishes it from the framework the previous section described. A high-income American household in 2025 receives the substantial portion of its income in the form of capital gains and qualified dividends, taxed at twenty percent (plus the three point eight percent net investment income tax established by the Affordable Care Act, for a top effective rate of approximately twenty-three point eight percent), while the wage-earning American household receives its income in the form of ordinary wages, taxed at marginal rates rising to thirty-seven percent (plus payroll taxes of seven point six five percent on the employee side). The structural feature of the contemporary American tax code is that capital income is taxed at substantially lower effective rates than labor income. The structural intent of the pre-1981 framework — that the highest-income population be constrained by high marginal rates on all categories of its income — has been substantially eliminated. The constraint that operated through the post-war period has been removed.

The structural reason the constraint has been removed is the political coalition described in The Donor Class. The capital-gains preference is the structural feature that the donor class most directly benefits from; the donor class is the constituency that has, across the post-1981 period, blocked every legislative attempt to restore the equalization that the 1986 Tax Reform Act had briefly established. The Clinton administration, under bipartisan pressure, widened the differential rather than narrowing it. The Bush administration extended the preferential treatment to dividends and reduced the rate further. The Obama administration, despite controlling unified federal government in 2009-2010, did not move to equalize the rates beyond the modest three point eight percent net investment income tax and the partial restoration of the pre-Bush capital-gains rate at the very top. The Biden administration’s 2021-2022 proposals to raise the capital-gains rate for high-income households were not enacted in the Inflation Reduction Act that emerged from the legislative process. The structural feature has remained in place across forty-four years of revisions because the structural feature is the one the donor class most directly benefits from preserving.

The 2017 Tax Cuts and Jobs Act, the most substantial reorganization of the American tax code since 1986, accelerated the structural pattern in two specific ways.¹⁵ The Act reduced the corporate rate from thirty-five percent to twenty-one percent — a rate reduction of approximately forty percent, the largest single-cycle corporate rate reduction in American tax history. The Act’s individual rate reductions were modest by comparison; the structural shift was on the corporate side. The Act also established the Section 199A pass-through deduction, allowing twenty percent of pass-through business income to be deducted from taxable income for the affected entities. The deduction’s principal beneficiaries, by Joint Committee on Taxation analysis, were high-income owners of pass-through entities — primarily the medical, legal, financial, and real-estate professionals whose income is structured through partnerships and S corporations.¹⁶ The combined effect of the corporate rate reduction and the Section 199A deduction was to further reduce the effective rate on capital and capital-related income, while leaving the wage-earning population substantially unchanged. The Act’s revenue cost was substantial — approximately one point five trillion dollars over ten years, by Congressional Budget Office scoring — and was financed principally through deficit expansion rather than offsetting revenue measures.¹⁷

The cumulative effect of the 1981-2017 sequence of statutory changes was the construction of a tax framework whose operational features were the structural inversion of the framework the 1913-1944 period had built. The high marginal rates that had constrained top-end accumulation were eliminated. The capital-gains preference that had been narrowed in 1986 was widened beyond any prior level. The corporate rate was reduced to a level that, in combination with the Section 199A deduction, produced an effective rate on capital income substantially below the rate on labor income. The estate tax exemption was raised across multiple revisions, reaching approximately twenty-seven million dollars per couple by 2024, exempting the substantial majority of estates from the estate tax that the 1916 Act had established to constrain dynastic wealth.¹⁸ The framework that had constrained the Gilded Age concentration the 1913-1916 statutes were enacted to address has been substantially dismantled. The concentration the framework constrained has, predictably, returned.

The Step-Up and the Inheritance

The technical feature of the contemporary American tax code that most directly enables intergenerational wealth concentration is the step-up in basis at death, codified at Internal Revenue Code Section 1014.¹⁹ The provision operates as follows. When a taxpayer dies, the cost basis of any inherited asset is “stepped up” from the deceased’s original cost basis to the asset’s fair market value at the date of death. The capital-gains tax that would have been owed on the appreciation accrued during the deceased’s lifetime is forgiven entirely. The heir inherits the asset at the stepped-up basis and, upon any subsequent sale, owes capital-gains tax only on appreciation accrued after the date of inheritance. The capital-gains tax on the deceased’s lifetime appreciation is permanently eliminated.

The structural consequence of the step-up provision is the elimination of the capital-gains tax as a constraint on intergenerational wealth transmission. A taxpayer who acquires a substantial portfolio of appreciated assets — equities, real estate, business interests — and holds those assets through retirement is incentivized, by the step-up provision, to never sell. The capital-gains tax is owed only on sale; the step-up at death erases the tax entirely. The taxpayer who holds appreciated assets through death and bequeaths them to heirs has, in effect, accessed the lifetime appreciation tax-free; the heir has accessed it on the same basis. The capital-gains tax that would have applied to the sale of the assets during the original taxpayer’s lifetime is, through the combination of the holding decision and the step-up provision, never paid. The Joint Committee on Taxation has scored the step-up provision as approximately seventy billion dollars in annual revenue cost, with the substantial majority of the benefit flowing to the top wealth quintile.²⁰

The combination of the step-up provision and the elevated estate tax exemption produces a structural inheritance system that is, in operational terms, distinctively favorable to the highest-wealth American households. An estate below the exemption threshold (approximately twenty-seven million dollars per couple in 2024) escapes the estate tax entirely; the heirs receive the assets at stepped-up basis, on which they owe no capital-gains tax until subsequent sale. An estate above the exemption threshold pays the estate tax on the portion above the exemption, but the inherited assets still receive the stepped-up basis, with the same elimination of the lifetime capital-gains tax. The combined effect is that the wealthiest American families can transmit substantial portions of their accumulated wealth across generations without the capital-gains tax that, in the absence of the step-up provision, would constrain the transmission. The estate tax as currently designed addresses only the top-end portion of the wealthiest estates; the step-up provision applies to all estates, and is the mechanism through which the substantial majority of intergenerational wealth transmission occurs.

The cumulative effect of the step-up provision, operating across multiple generations of accumulation, is the structural mechanism by which dynastic American wealth has, across the post-1981 period, concentrated at rates that the 1916 estate tax framework was specifically designed to prevent. The Walton family (Walmart heirs), the Mars family, the Cargill-MacMillan family, the Koch family, the Mellon family, the Pritzker family, and the broader category of family-office-managed dynastic American wealth have, across the post-1981 period, expanded their share of national wealth through the same step-up mechanism that the 1916 Act was constructed to constrain.²¹ The constraint has been eliminated; the concentration has resumed; the trajectory has been the trajectory the pre-1916 framework allowed and that the 1916 framework was constructed to interrupt.

The step-up provision is the technical feature; the political feature is that the step-up provision has been preserved across forty-four years of revisions despite the substantial empirical case against it and despite proposals from both parties to modify it. The Carter administration considered eliminating the step-up in 1976; the proposal was abandoned under intense lobbying opposition.²² The Obama administration’s 2015 budget proposal would have eliminated the step-up for individual estates above approximately one hundred thousand dollars; the proposal was not adopted by Congress. The Biden administration’s 2021 American Jobs Plan and American Families Plan included elimination of the step-up; the provision was dropped from the legislative compromise that became the Inflation Reduction Act of 2022.²³ The pattern is the pattern that The Donor Class essay described: the structural reform that addresses the principal mechanism of wealth concentration is consistently advanced and consistently blocked, by the lobbying coalition that the wealth concentration funds.

The Two Parties’ Two Failures

The Democratic position on federal taxation across the post-1981 period has been, in operational terms, the acceptance of the post-Reagan baseline as the political starting point for any reform proposal. Successive Democratic presidential administrations and congressional majorities have proposed modifications at the margins — restoration of the pre-Bush rates on top earners, expansion of the Earned Income Tax Credit, modest closures of named loopholes, the three point eight percent net investment income tax of the Affordable Care Act, the corporate alternative minimum tax of the Inflation Reduction Act — without proposing structural restoration of the pre-1981 framework. The structural features the inversion produced — the capital-gains preference, the step-up in basis, the corporate rate level, the elevated estate tax exemption — have been preserved across Democratic and Republican administrations alike, with modifications that have not changed the operative system the inversion produced.

The Democratic coalition’s specific failures on the structural reforms have followed a consistent pattern. The capital-gains rate has been raised modestly under Democratic administrations (Clinton 1993, Obama 2013) but has not been equalized with the ordinary income rate as the 1986 Tax Reform Act had briefly established. The step-up in basis has been proposed for elimination under Democratic administrations (Carter 1976, Obama 2015, Biden 2021) and has not been eliminated. The estate tax exemption has been raised under Democratic administrations as part of compromise legislation (the 2010 extension of the Bush-era cuts, the 2012 fiscal-cliff compromise) and has not been substantially lowered. The corporate rate has been preserved or modified at the margins under Democratic administrations and has not been restored to the pre-2017 level. The carried-interest treatment that allows private-equity and hedge-fund managers to characterize compensation as capital gains has been preserved across Democratic administrations despite repeated rhetorical commitments to closure.²⁴ The Section 199A pass-through deduction was preserved in the 2022 Inflation Reduction Act despite Democratic-party platform opposition.

The reason the Democratic coalition has failed on the structural reforms is the reason The Donor Class essay identified at the structural level. The Democratic coalition’s principal donors — the financial-services industry, the technology industry, the real-estate industry, the higher-end professional class — are the constituencies whose interests the post-1981 tax framework most directly serves. The donor class that funds Democratic presidential campaigns and the donor class that funds Republican presidential campaigns overlap substantially; the policy positions the two donor classes most consistently support are the positions that protect the capital-income preferential treatment, the step-up in basis, and the elevated estate tax exemption. The Democratic coalition’s failure to enact the structural reforms is not principally a matter of insufficient majorities or insufficient public support; it is the operational expression of the donor-class constraint on the legislative coalition. The reforms that the Democratic platform has consistently proposed are the reforms the donor class has consistently blocked. The blocking has been operationally effective across forty-four years of Democratic legislative attempts.

The Republican position has been the structural opposite: the framework reductions on capital and corporate income have been the principal Republican legislative priority across the same period, advanced under every Republican unified-government opportunity (1981, 2001-2003, 2017) and defended in the legislative compromises of the intervening periods. The Republican coalition has, in operational terms, been the principal driver of the inversion the previous sections described. The Republican framework on taxation has been internally coherent across the period: lower rates on capital and corporate income, broader exemptions, simplified compliance, deficit financing of the resulting revenue gap. The framework’s empirical results — the reduction of the federal revenue base as a share of GDP, the substantial expansion of federal debt across periods when the rate reductions have been enacted, the documented absence of the supply-side investment response that the framework predicted — have not modified the framework’s operational priorities.²⁵ The Republican coalition has continued to advance the framework’s principal components across each available legislative cycle.

The convergent failure of both parties has been the absence of any serious legislative proposal to restore the structural features the 1913-1944 framework had constructed. The high marginal rates have not been advanced as a serious policy proposal in either party’s legislative history since the early 1980s. The pre-1981 estate tax exemption has not been advanced. The pre-1986 capital-gains differential treatment has not been advanced. The high-tax framework that the post-war American economy operated under for thirty-five years (1945-1980) is, in the contemporary policy debate, treated as historical anomaly rather than as an operative alternative to the contemporary framework. The treatment is structurally incorrect: the pre-1981 framework operated successfully across the period that produced the most substantial American middle-class expansion in the country’s history, against a backdrop of substantial economic growth and on a revenue base that funded the substantial public investments — interstate highways, public university expansion, the GI Bill, the early Medicare and Medicaid programs — that the contemporary American policy debate frequently invokes nostalgically while declining to fund at comparable levels.

The Cascade That Closes

The tax framework described in the previous sections operates, considered in isolation, as a structural mechanism that has produced the wealth-concentration outcomes the contemporary American distribution exhibits. Considered against the AI labor cascade, the housing carrying-cost cascade, the healthcare extraction mechanism, the student loan cascade, and the campaign-finance lock-in described in the previous essays in this series, the framework becomes the structural element that converts each of those mechanisms into its operative form.

The AI Implosion identified the wage cascade and the wealth transfer the cascade produces.²⁶ The wealth transfer the cascade produces flows into the asset categories — equities, real estate, business interests — whose appreciation receives the preferential capital-gains treatment described in the previous sections. The household whose wage income is being compressed by the AI cascade is taxed, on the residual wage income, at the ordinary-income marginal rates that have been maintained across the post-1981 period. The capital owner whose return is being expanded by the same cascade is taxed, on the resulting capital appreciation, at the preferential capital-gains rates that the same period has established. The structural consequence is that the wealth transfer the AI cascade produces is, on the contemporary tax framework, lightly taxed on the receiving end and heavily taxed on the diminished side. The tax framework operates as the multiplier on the underlying cascade.

The Quiet Foreclosure described the mechanism by which institutional buyers acquire single-family residential through the carrying-cost cascade.²⁷ The institutional buyers, organized as REITs or private-equity partnerships, are taxed on the resulting rental income and on the underlying property appreciation through the pass-through and capital-gains structures the post-1981 framework has established. The displaced homeowners, who in the cascade scenario sell at distressed prices and become renters, do not benefit from the preferential treatment because they have neither the asset structure nor the tax-planning capacity to access it. The structural feature compounds: the institutional buyers acquire the assets at lower effective tax cost than the displaced homeowners had been carrying them, while paying the displaced homeowners — through the eventual rental relationship — at prices that include the institutional buyers’ tax and capital costs. The framework operates against the displaced homeowner at every step of the conversion.

The Accidental System described the medical extraction mechanism that operates against the household with insufficient savings.²⁸ The household whose savings are insufficient to absorb a medical event is, in the contemporary tax framework, the household whose income has been subject to ordinary-income taxation throughout its earning years. The household whose savings are sufficient to absorb the same event is the household whose income has, in substantial part, been subject to the preferential capital-income taxation. The structural feature operates against the medical-event household at the moment of the event: the framework that produced the savings differential during the earning years is the framework that produces the bankruptcy-versus-absorption differential at the moment of the event.

The Credential and the Debt described the student loan extraction mechanism that operates against the credentialed cohort whose entry-level wages the AI cascade is now compressing.²⁹ The borrower carrying student debt is taxed on her ordinary wage income at the rates that have been preserved across the post-1981 period, while the lender — the federal government — does not bear the underlying default risk. The structural feature is that the borrower’s tax burden compounds with the loan service against the income the AI cascade is compressing. The capital owner whose appreciation is being financed by the same federal apparatus, through the federal commitment to maintain the educational financing system without addressing the institutional pricing, is taxed on the resulting appreciation at the preferential capital-income rates.

The Donor Class described the political-economy lock-in by which the donor class blocks the structural reforms that would constrain each of the previous mechanisms.³⁰ The structural feature of the lock-in is that the donor class is the constituency whose income and wealth are most directly served by the post-1981 tax framework, and that the political coalitions whose votes would be required to modify the framework are funded principally by the donor class whose income the framework most favorably treats. The framework is the operating mechanism through which the donor class’s wealth is preserved and expanded; the donor class is the constituency whose lobbying prevents the framework from being modified. The circle is closed at the structural level the previous essay described.

The cumulative effect of the tax framework operating across all five of the prior cascades is the structural condition of the contemporary American household economy. The household whose wage income has been compressed by the AI cascade, whose housing carrying costs have been escalating against the compressed income, whose medical exposure has been growing against the inadequate savings, whose student debt has been compounding against the diminished wage premium, and whose access to the political coalitions that would address any of the cascades has been blocked by the donor-class lock-in is, in the contemporary tax framework, also the household whose marginal income is taxed at rates substantially higher than the marginal income of the capital owner whose appreciation each of the cascades has been producing. The framework is the operating multiplier on every other extraction mechanism the series has identified. The fourth-settlement reforms the previous essays have proposed are, in operational terms, financed through reform of the framework. The framework that exists cannot finance them; the framework that could is the alternative the next section describes.

What’s at Stake

The American political economy has confronted the structural question of how the federal tax system should be designed three times before, and each time produced a settlement distinctive to its moment.

The Sixteenth Amendment settlement of 1913-1916, established under Wilson, created the federal income and estate tax framework that constrained American capital concentration across the post-Progressive period. The settlement was the first explicit federal anti-oligarchic instrument and operated, with marginal modifications, across the four decades that produced the post-war American middle class.

The 1986 reform settlement, established under Reagan and O’Neill, restructured the framework around lower marginal rates and broader bases on the framework that the lower rates would produce equivalent revenue with less distortion. The settlement maintained the pre-1981 framework’s structural features — capital-gains parity with ordinary income at the top, substantial corporate taxation, meaningful estate taxation — at lower nominal rate levels.

The post-1986 framework that has accumulated across the 1990-2017 period dismantled the structural features the 1986 settlement had preserved. The capital-gains preferential treatment was widened progressively. The corporate rate was reduced substantially. The estate tax exemption was raised to levels that exempt the great majority of estates. The framework that emerged is, in operational terms, the inversion of the 1913-1944 framework — favoring capital income over labor income, intergenerational transmission over consumption, accumulation over distribution. The framework has produced the wealth-concentration outcomes the contemporary American distribution exhibits.

A fourth settlement is now required, and it is structurally a partial restoration of the framework the 1913-1944 sequence had constructed, modified for the contemporary economy and the contemporary political coalitions. The Intelligent Party’s tax framework, articulated in the platform’s taxation position, has five components that together address the structural features the previous sections diagnosed.³¹

The first component is the equalization of capital gains and qualified dividends with ordinary income for the highest-income brackets, with a small exclusion preserving favorable treatment for middle-class retirement savings and modest taxable brokerage accounts. The component restores the 1986 Tax Reform Act’s brief equalization, on a basis that addresses the principal critique of the 1986 framework — that the equalization affected middle-income retirement savers as well as high-income capital holders — by preserving favorable treatment for the savings categories the middle-class American household uses for retirement.

The second component is the elimination of the step-up in basis at death. The component closes the structural feature that has, across the post-1981 period, allowed dynastic American wealth to transmit capital appreciation across generations without the capital-gains tax that would otherwise apply. The component does not eliminate the inheritance; it eliminates the elimination of the capital-gains tax on the inherited appreciation. The estate tax continues to apply at the threshold; the step-up no longer extinguishes the lifetime appreciation.

The third component is the increase in estate tax rates and the lowering of the exemption to levels that affect the truly dynastic wealthy rather than the contemporary inflated-exemption population. The component restores the 1916 Act’s framework, modified for contemporary asset valuations and exempting middle-class family farms and businesses through the appropriate threshold structure.

The fourth component is the financial transactions tax: a small per-trade fee on equity and bond transactions, structured at a rate that is invisible to the ordinary-investor population (a rate of approximately one-tenth of one percent on equity transactions would impose, on the typical retail investor’s annual trading volume, a cost in the low single digits of dollars) but meaningful across the high-frequency-trading volumes that constitute the substantial majority of contemporary equity-market activity. The component, modeled on the European Union’s various financial-transactions-tax proposals and on the Tobin-tax framework that the comparative literature has developed since the 1970s, dampens speculative activity at the margin while raising significant revenue from the segment of capital-market activity that has the smallest claim on preferential tax treatment.

The fifth component is the consolidation of fragmented federal social-program taxation into the Country Profit Sharing fund, the structural feature that the platform’s taxation position identifies as the operational mechanism through which the broader fourth-settlement framework is financed. The component is, in tax terms, a restructuring of the existing tax base rather than an expansion of it: the FICA payroll taxes for Social Security, the federal expenditure for SNAP and TANF and SSI and EITC, and the comparable categories of federal social-program spending consolidate into a single shared dividend distributed equally to all American citizens. The tax base does not grow in the aggregate; it redirects. The political effect is the conversion of the resented welfare apparatus the post-1981 Republican coalition has effectively framed into a shared inheritance system that addresses the donor-class-driven concentration on the underlying tax framework. The administrative effect is the elimination of the eligibility-checking bureaucracies that the fragmented social-program structure currently requires. The mechanism’s broader case is the case the platform’s CPS framework develops at length; for present purposes, the component’s tax-policy significance is that it operates as the financing structure for the broader fourth-settlement reforms the previous essays have described.

The five components, taken together, address the structural problem the previous sections identified: the inversion of the 1913-1944 framework that has, across forty-four years, produced the wealth concentration the contemporary American distribution exhibits. The components do not return the framework to the 1944 ninety-four percent top marginal rate or the 1944 estate tax structure; they restore the structural intent of the 1913-1944 framework — the constraint on top-end accumulation, the substantial taxation of intergenerational transmission, the parity of capital and labor income at the highest brackets — within the institutional and political constraints of the contemporary American context. The framework is, in this respect, a structural continuity with the framework the post-Progressive American Congress constructed and the post-1981 political coalitions have dismantled.

The political coalition required to enact the five components does not currently exist. The conditions under which it might assemble are the conditions the multi-axis cascade is now producing. The framework’s principal beneficiaries are the substantial majority of American households whose wage income is taxed at the post-1981 ordinary-income rates and whose access to the preferential capital-income treatment is structurally limited by the asset distribution the post-1981 period has produced. The framework’s principal opponents are the donor class whose wealth the post-1981 framework most directly serves and whose lobbying complex is the structural barrier to the assembly the framework would require.

The comparative record is, in this case as in the others, instructive. Every other major developed country operates a tax framework substantially more progressive than the contemporary American framework, with substantially higher effective taxation of capital income, substantially more aggressive estate taxation, and substantially lower wealth concentration as the cumulative output. None of those countries has experienced the wealth-concentration outcomes the United States has produced; none of those countries faces the household financial cascade the previous essays have described at the comparable scale; none of those countries operates the political-economy lock-in described in The Donor Class at the comparable severity. The structural alternative is not theoretical. It operates in every comparator democracy with which the United States routinely compares itself.

The realism the previous essays have called for, applied to taxation, is the realism that the structural reform is achievable on the specific architecture The Intelligent Party has proposed; that the architecture has been designed to address the political feasibility constraints that have prevented the broader reform attempts; that the principal obstacle to its enactment is the donor-class lock-in described in The Donor Class, operating in this case through the financial-services lobbying complex and the broader corporate political-spending apparatus that the post-Citizens-United era has institutionalized. The conditions under which the lock-in breaks are the conditions under which all of the fourth-settlement reforms simultaneously become available. The tax reform, like the housing reform and the healthcare reform and the education reform, is one component of a larger settlement. It cannot, on the trajectory the series has described, be enacted in isolation. It will, when the assembly that the next decade may produce assembles, be enacted alongside the other components.

The essay about the American tax system that someone writes in 2040 will describe either the construction of the fourth-settlement framework or its refusal. The constituency that would benefit from the framework is the constituency the post-1981 framework has, across forty-four years, structurally disadvantaged: the substantial majority of American households whose income is taxed at the ordinary-income marginal rates and whose access to the preferential capital-income treatment is structurally limited. The constituency exists. Its political assembly has not yet occurred. The structural conditions for the assembly, on the trajectory the previous essays have described, will be in place within the next decade.

The tax code that built the donor class is the tax code that continues to be defended by the donor class. The tax code that would dismantle the structural conditions of the donor class is the tax code the structural conditions of the donor class have, across forty-four years, prevented from being enacted. The fourth-settlement framework, on the trajectory the series has described, is the assembly under which the dismantling becomes operationally available. The framework is, in this respect, the structural lever on which every other component of the broader settlement turns.

The realism is the realism Theodore Roosevelt described in 1907: that “no system of government can long maintain itself in which the great fortunes are not subject to the operation of the laws which are operative against the small fortunes.”³² The system Roosevelt described as required has, in the contemporary American context, been substantially dismantled. The reconstruction is the assembly the next decade will either produce or refuse.
