Between 1948 and 1973 American capitalism shared: a GM-UAW contract with pensions, health insurance and cost-of-living wages set a pattern, union density reached one worker in three, and the gap between rich and poor narrowed. Fortune called it the Treaty of Detroit. The episode celebrates what it delivered, then reads the fine print about who was left out.
Skeptics say the accord was a productivity deal that traded away labor's voice and contained its own expiration date, while defenders note a generation of compounding gains. Some historians question whether an accord existed at all, and the Wagner Act's exclusions are read as a racial bargain or administrative convenience.
