In Fear the Boom and Bust, John Maynard Keynes and F. A. Hayek, two of the great economists of the 20th century, come back to life to attend an economics conference on the economic crisis. Before the conference begins, and at the insistence of Lord Keynes, they go out for a night on the town and sing about why there’s a “boom and bust” cycle in modern economies and good reason to fear it.
