There’s an old Southpark episode (Die Hippie, Die, Season 9, available on iTunes) in which hippies invade the town and only Cartman can stop them. Cartman soberly classifies hippies into three groups: giggling stoners, drum circle hippies, and worst of the lot, college know-it-all hippies.
With the OWS protests and now the “strike” by Harvard students who walked out of a basic economics class, I keep thinking of that episode. I can’t post the episode – it’s too rude and probably a violation of copyright. But here’s a link to a great 5 minute interview with the Harvard economics professor who taught the class. In it, he discusses the growing income inequality in America and the different approaches liberals and conservatives take to it.
