Digging a bit further (and noting a slight slant in the video), the creators' Hayekian leaning becomes apparent. The education value (funny youtube video + clever rap + macroeconomics!) is extremely high. So I obviously posted it on the class website for my students when we covered macro development.
The ideas of economists and political philosophers, both when they are right and when they are wrong, are more powerful than is commonly understood. Indeed the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influence, are usually the slaves of some defunct economist. -JM Keynes
