From 1948 to 1973, US worker productivity grew by about 96 percent. Average wages, adjusted for inflation, grew by about 91 percent. The two lines tracked each other. From 1973 to 2025, productivity grew another 80 percent. Real wages grew about 13 percent. The divergence shows up in the same BLS series the Economic Policy Institute, the Heritage Foundation, the Bipartisan Policy Center, and the Federal Reserve all cite, with minor variations in methodology.
There is a technical argument inside the data. Using total compensation including benefits rather than wages alone narrows the gap somewhat, because health and retirement costs have grown faster than cash wages. Using the PCE deflator instead of CPI also narrows it. Every reasonable methodological choice still produces a substantial wedge. A Federal Reserve Bank of San Francisco study published in 2024 reconciled the competing measures and put the residual gap at roughly 45 percentage points, even after the most generous adjustments. Reuters, the Wall Street Journal, and the New York Times have all run feature coverage on the wage-productivity gap in the last 18 months.
The income distribution data tells a corresponding story. Corporate profits as a share of GDP have roughly doubled since the 1970s. The wage share of GDP has fallen by a comparable amount. Research by Thomas Piketty, Emmanuel Saez, and Gabriel Zucman, which has been independently replicated, finds the top 1 percent of US earners captured roughly two-thirds of inflation-adjusted income growth since 1980. The top 0.1 percent captured a disproportionate share within that. The IRS Statistics of Income data confirms the broad pattern.
The drivers economists generally identify are a stack rather than a single cause. Private-sector union density fell from about 24 percent in 1973 to under 7 percent in 2025. Corporate governance shifted toward shareholder primacy in the 1980s and 1990s, with executive compensation tied increasingly to share price. Federal minimum wage purchasing power peaked in 1968 and has eroded since. Antitrust enforcement narrowed substantially from the late 1970s onward, allowing labor-market concentration to rise. Trade liberalization moved manufacturing exposure to import competition without paired transition support. Each of these decisions was made over multiple administrations of both parties.
The legislative items pending that intersect with the gap are concrete. The PRO Act has stalled in the Senate for three consecutive sessions. The current administration’s antitrust agenda has produced active cases at DOJ and FTC but no major statutory change. Tax provisions from the 2017 law expiring at the end of 2025 are now in negotiation, with the treatment of pass-through income and the corporate rate the principal axes. The outcome of those negotiations will move the post-tax distribution measurably. Anyone framing the wage gap as inevitable or natural is contradicting both the data and the legislative calendar.
