The U.S. federal tax code reads like a revenue document and functions like an asset-protection one. The basic move is the same throughout: income from labor gets taxed at full ordinary rates, while income from owning things — capital gains, dividends, inherited assets, real estate appreciation — gets taxed lightly, deferred indefinitely, or not at all. The result is a system that collects most of its revenue from working households while quietly helping wealthy ones compound across generations.
The capital gains gap
A worker earning $200,000 in salary pays an effective federal rate north of 24 percent on the income above the lower brackets, plus payroll taxes. A passive investor who realizes $200,000 in long-term capital gains pays 15 percent or 20 percent depending on income, with no payroll tax. The same household earning the same money pays radically different rates depending on whether the income came from work or ownership. The justification offered — that capital is mobile and needs lower rates to stay invested — is contested in the academic literature, with serious economists like Emmanuel Saez and Gabriel Zucman arguing the elasticity assumptions are overstated. Whatever the policy rationale, the practical effect is that the tax code is structurally biased toward households who already own assets.
Step-up in basis: the inheritance giveaway
The single largest tax break in the code, by lifetime impact, is step-up in basis at death. When an asset is inherited, its cost basis resets to fair market value, erasing all the capital gains that accumulated during the original owner’s lifetime. A founder who built a company over forty years and dies holding $500 million in stock with a $1,000 cost basis transfers that stock to heirs at a fresh $500 million basis. The capital gains tax that would have been owed on $499,999,000 of appreciation simply disappears. The estate may owe estate tax above the exemption ($13.99 million per individual in 2025, doubled for couples), but the layered effect is that most multi-generational wealth in America has never been taxed at the capital gains level. The Joint Committee on Taxation estimates this provision alone costs roughly $40 to $60 billion a year in foregone revenue.
The pass-through and depreciation toolkit
For active business owners and real estate investors, additional layers compound the advantage. Pass-through deductions added in 2017 lower effective rates for qualified business income. Real estate depreciation generates paper losses that offset other income while properties appreciate in market value. 1031 exchanges defer gains indefinitely on real estate sales. Carried interest treats hedge fund manager compensation as capital gains rather than ordinary income. Each of these provisions has a stated policy rationale; collectively, they form a parallel tax regime for asset owners that bears almost no resemblance to the W-2 system most Americans actually face.
The bottom line
The U.S. tax system isn’t failing to tax wealth. It’s been engineered, provision by provision, over decades, to specifically not tax it. Calling that a flaw misreads the design. It’s a feature for the people the design serves, and the working households filling out their 1040s every April are the ones funding the wealth-preservation engine that doesn’t apply to them.
