Abstract
During the twentieth century, Congress's power to regulate commerce grew sensationally while its human rights powers atrophied. This strange phenomenon originated in the choice, made by lawyers and politicians in the early 1930s, to base labor rights statutes like the Wagner Act on the Commerce Clause instead of the Thirteenth Amendment. Unions and workers argued that the rights to organize and strike made the difference between freedom and involuntary servitude. But a bevy of progressive lawyers who styled themselves friends of labor undermined labor's Thirteenth Amendment theory. The article argues that this clash reflected not merely tactical differences among allies, but fundamentally conflicting constitutional goals. It contends that the Supreme Court upheld the Wagner Act not because of the lawyers' Commerce Clause arguments, but because workers staged a series of sit-down strikes that confronted the swing justices with a choice between industrial peace or war. Afterward, unions and workers interpreted the Wagner Act decisions as victories for labor freedom, but the Act's Commerce Clause foundation pointed in a different direction - one leading to fateful distortions in the jurisprudence of congressional powers.
