Prohibition’s Unraveling and the 21st Amendment
Civics In A Year
Prohibition didn’t just give America speakeasies and gangsters it gave us one of the clearest stress tests of the U.S. Constitution. We dig into a paradox that surprises a lot of people: national alcohol consumption drops sharply under the 18th Amendment, yet the country still turns against the policy because enforcement breeds a culture of lawlessness and resentment that politics can’t ignore.
The real drama sits in federalism. Our conversation follows the repeal movement’s most consistent argument: alcohol rules don’t fit a single national template, and the 18th Amendment’s odd “concurrent authority” language leaves a basic question unanswered. Are states required to enforce prohibition, allowed to enforce it, or free to step back entirely? That ambiguity sparks resistance, uneven compliance, and a constitutional debate that sounds strikingly modern, especially when you connect it to the anti-commandeering principle and the limits of federal power.
We also track how the Great Depression changes the incentives. Liquor taxes once provided major government revenue, and prohibition replaces that income with enforcement costs. Add the 1932 political battlefield, Hoover’s commitment to enforcement, and FDR’s tactical move to treat beer as non-intoxicating, and repeal starts to look inevitable. We close with the 21st Amendment’s unique ratification by state conventions and why Section Two still protects dry states and dry counties long after repeal.
