The Great Depression isn’t just history. It’s the moment we keep dragging into today’s fights about stimulus, deficits, inflation, and what government should do when millions can’t find work. We sit down with Dr. Nicholas O’Neill from Arizona State University’s School of Civic and Economic Thought and Leadership to make the Keynes vs Hayek divide clear, concrete, and rooted in the world that shaped it.

We rewind to a time when “economic crisis” often meant weather, harvest failure, and the price of bread, then follow the shift into industrial capitalism where recessions look like collapsing demand, shuttered factories, and mass unemployment. From there, we walk through the 1920s boom, speculative bubbles, tightening monetary conditions, the 1929 crash, and the deflationary spiral that turned fear into bank failures and prolonged joblessness.

Hayek’s Austrian economics warns that manipulating money and credit can corrupt price signals and lock in bad decisions, making downturns worse. Keynesian economics argues the opposite danger: when uncertainty spikes, people and firms can hoard cash, starving the economy of spending and trapping it in high unemployment unless public policy jump-starts demand through countercyclical fiscal spending. We also clear up a common myth about the New Deal, then land on an unexpected civics takeaway: Keynes and Hayek modeled serious, respectful disagreement in private letters, even while arguing in public.
