The billionaire class is looting the productive capacity of the American economy—and the economics profession is stealing the policy debate to protect that extraction. Here are the numbers. According to the Census Bureau, the income ratio between the 90th and 10th percentiles rose from 8.7 in 1976 to 12.6 in 2024. The wealth of the 400 richest Americans has grown by a factor of 15 since 1982, while median family incomes have less than doubled.
Five economists have published competing solutions: a wealth tax (Saez), deregulation (Cochrane), upward mobility (Chetty), union revitalization (Boushey), and applied research centers (Hubbard). Saez at least aims his wealth tax at the extraction mechanism, acknowledging the billionaire class’s 24 percent effective tax rate falls below the 30 percent average. But his proposal treats the symptom—a revenue shortfall—rather than the disease: the realization doctrine and the corporate subsidy that allow those gains to escape tax. Cochrane’s deregulation pitch, delivered from the Hoover Institution, frames capital gains enforcement as confiscatory—“burning evil capitalist businesses”—a calculated distortion that ignores the reality: the power to direct investment is already captured by the private sector to prioritize executive dividends over workforce stability. The state power he warns against is already exercised by billionaire heirs who concentrate gains while median CEO pay sits at 200 times the worker’s wage. Chetty’s mobility, Boushey’s labor power, Hubbard’s work-support credits: all treat billionaire accumulation as a technical variable to be managed, not a structural extraction enabled by the tax code.
The structural reality is not the degree of inequality, but how the tax code permits donor-class accumulation to operate outside the fiscal accountability applied to wage earners. Those of us who scored the 2017 corporate-rate reduction know the mechanism in practice. Dynamic scoring promised growth and wage effects. The actual outturn was a transfer of capital from the tax base to the top decile’s unrealized gains—specifically, a massive, repatriation-driven surge in share repurchases that funneled tax savings straight into equity prices rather than production or paychecks. The realization requirement of Section 1001 of the Internal Revenue Code means a billionaire can accumulate billions in market appreciation without generating a single dollar of taxable income. The Joint Committee on Taxation scores revenue under current law, which preserves these provisions.
The editorial apparatus frames the five economists as debating how much inequality to reduce. This is wonk-laundering. The structural feature is not the degree of inequality, but how the law penalizes wage income at a higher effective rate than capital accumulation. The current-law baseline is not a neutral forecast; it is a description of the policy choice to subsidize retained earnings through tax expenditures that never appear as outlays. The debate over a wealth tax is wonk-laundering: we are laundering billionaire theft through the language of fiscal discipline. The score is the score. The author of the bill does not get to grade it.
Any serious attempt to resolve this requires looking beyond taxation alone. As Heather Boushey argues, we must revitalize the anti-monopoly tools of the 1800s, strengthen labor unions to restore worker leverage, and aggressively invest in public health and green-energy infrastructure to prevent the calcification of wealth concentration. Market-opportunity rhetoric cannot mask the fact that wealth inequality is now a structural barrier to productivity.
We are faced with three choices. We can continue to pretend that a wealth tax is a threat to democracy, thereby protecting the actual mechanism of wealth concentration. We can adopt the evidence-backed path of targeted human capital investment, as Raj Chetty and Glenn Hubbard have independently argued. Or we can accept that the “land of opportunity” has become a wealth-extraction machine for the 0.0002 percent. There is no fourth option: we must stop taxing labor to subsidize the retention of billionaire wealth and start taxing the extraction of that wealth at its source.
