Loopholes Compound: Burden Falls Downward

The Structural Arithmetic

Washington, D.C. — The American tax code operates less as a flat ledger and more as a layered architecture of preferential treatment whose distributional consequences are, by design, invisible to the median taxpayer. Since the 2017 Tax Cuts and Jobs Act lowered the statutory federal corporate rate to 21 percent, the marginal incentive for large multinationals to repatriate offshore earnings or execute inversion mergers has attenuated—but the effective tax rates realized by the top decile of filers with more than ten billion dollars in assets remain a fraction of the 37 percent top ordinary-income bracket that binds the vast majority of wage-earners.

The Dual-Rate Problem

Capital gains and qualified dividends are taxed at a top marginal rate of 20 percent, plus a 3.8 percent Net Investment Income Surtax, capping the federal load at 23.8 percent. Carried interest income—compensation paid to general partners of private-equity and hedge-fund vehicles—is subjected to long-term capital-gains treatment despite functioning as labor income in economic substance. The result: a fund manager generating a $500 million carry on a seven-year hold pays a federal rate roughly 13 percentage points below a senior engineer at the same income multiple. No legislative provision in the current code reclassifies carried interest as ordinary compensation, and the 2017 TCJA extended the holding-period requirement to three years, deferring the tax trigger further.

Corporate Avoidance Architecture

The 21 percent headline rate is a ceiling, not a floor, for effective burdens. Mega-corporations deploy a stack of mechanisms—research-and-development super-deductions, accelerated Section 168 bonus depreciation (100 percent in 2022, phasing to 80 percent in 2023 and 66 percent in 2024), state-level tax credits, transfer-pricing adjustments within multinational groups, and the indefinite deferral of foreign income under the post-TCJA participation-exclusion regime—to compress their global effective rates well below the statutory figure. The Congressional Budget Office has long estimated annual non-entitlement tax expenditures in the region of $1.5 trillion or more, the majority of which disproportionately benefit high-income households and large entities.

The Burden Shift

Because federal revenue foregone through these channels is not recovered, the fiscal gap is bridged by three mechanisms that land disproportionately on the non-wealthy:

• Mechanism
• Who Bears It
• Regressivity

• Payroll tax (7.65% employee + 7.65% employer, capped at ~$168,600 in 2024)
• Wage-earners; cap makes effective rate progressive within wage strata but regressive in share-of-total-income
• Moderate–High

---

• State and local income + property taxes
• Homeowners in high-assessment jurisdictions; renters via pass-through to landlords; sales taxes on consumption
• Regressive in relative terms

• Deficit financing (Treasury borrowing)
• Distributed via interest on national debt; future tax liabilities; inflation via monetization
• Intergenerational regression {% /table %}

The payroll-tax cap, first introduced in 1935 and adjusted for wage indexing, means a household earning $3 million in a year pays the same Social Security and Medicare FICA as a household earning $170,000. The incremental income above the cap is untaxed at the federal payroll level. Combined with the capital-gains and carried-interest preferences, the top 1 percent of income earners—concentrating roughly a third of national wealth—carry a blended effective federal-plus-state tax rate that, in multiple published analyses, falls below 20 percent, approaching the single-digit effective rates of large corporate filers.

Infrastructure Consequence

Federal surface transportation and water infrastructure trusts, already underfunded by decades of earmark-driven diversion, receive a shrinking share of general revenue. State and local governments, which account for roughly 80 percent of public-asset maintenance, are pushed to raise property and sales taxes on residential and consumer bases. A family in a Rust-Belt suburb pays a 30 percent state sales tax on groceries and utilities while a multinational with a $40 billion global revenue base parks $6 billion in Irish-domiciled captive financing entities paying an effective sub-7 percent blended rate. The asymmetry is structural, not cyclical.

Political Inertia

The lobbying expenditure differential is not incidental. Industry groups representing the top 0.1 percent of income earners devote more than four times the annual lobbying spend of the largest organized-labor and small-business federations combined, as tracked by OpenSecrets. This expenditure asymmetry maps onto the legislative agenda: proposals to repeal the capital-gains/corporate-rate differential, to reclassify carried interest, or to raise the payroll-tax cap are introduced annually and consistently stall in committee or are gutted in conference. The tax code’s distributional architecture is not an accident of legislative drafting; it is a maintained equilibrium.

The Unvarnished Synthesis

Tax policy in the United States functions as a fiscal extraction system optimized for capital formation at the top end of the distribution and a subsidized public-capital base for the middle. The middle and lower-income cohort funds roads, schools, transit, and water infrastructure through a composite of payroll levies, consumption taxes, and property assessments while the entities that generate the greatest marginal demand on those same assets—mega-corporations, ultra-high-net-worth individuals—pay a structurally discounted share. Closing that gap requires not a rate adjustment but a re-architecture of the code’s preferential stack: recategorization of carried interest, elimination of the payroll cap, a global minimum tax enforced domestically, and sunset of indefinite deferral provisions. Absent that re-architecture, the burden gradient steepens every fiscal year, and the infrastructure deficit compounds.

Forward Vector

The next legislative cycle will test whether the post-2025 fiscal environment—heightened by AI-driven labor substitution and a rising sovereign debt-to-GDP ratio—forces a recalibration. The political arithmetic, however, remains unchanged: those who benefit from the current structure hold disproportionate legislative access, and the cost of inactivity is borne by those with the least. The loop is closed. The variance, by design, accumulates downward.
