I find a dearth of funny economics-related videos on the web, so I figured when I find a great one, it should be passed on to Fazed. Hayek and Keynes are the founders of the two competing macroeconomic theories, with starkly opposed views. Hayek believes in the free market and any government intervention prolongs depressions, whereas Keynes believes that governments can intervene to shorten recessions (among the differences). This video defines the description much better than I just did, without needing an economics background to understand, plus it's put in rap form, so you kids will think its catchy.
