The hourly compensation of a typical worker grew in tandem with productivity from 1948–1973. That can be seen in Figure A, which presents both the cumulative growth in productivity per hour worked of the total economy (inclusive of the private sector, government, and nonprofit sector) since 1948 and the cumulative growth in inflation-adjusted hourly compensation for private-sector production/nonsupervisory workers (a group comprising over 80 percent of payroll employment). After 1973, productivity grew strongly, especially after 1995, while the typical worker’s compensation was relatively stagnant. This divergence of pay and productivity has meant that many workers were not benefitting from productivity growth—the economy could afford higher pay but it was not providing it.
