Maybe there's a little truth to that. I first read Marx in a political science class taught by a left-leaning professor with a beard and Birkenstock sandals who fit the role beautifully. But we also studied Adam Smith and David Hume and John Maynard Keynes and John Stuart Mill and a handful of others during the crash course in the masterworks of the field. It was one of the most challenging and informative classes I've ever taken.
