Robert Samuelson: my battle with US economic theories

I started in college majoring in business-economics.  I did so poorly.  I never was able to finish in class.  I took a class on economics where the main textbook by the American economist, Robert Samuelson (often confused with the Washington Post's columnist, Robert J Samuelson--no relation).  I sat in class in frustration and was already a very loyal and dogmatic Marxist and would only wait for the opportunity to attack the teacher and to defend Marxism.  It did not go well in class at all, and there was such acrimony between me and the teacher that students rolled their eyes as soon as the two of us would go at it.  I switched majors shortly thereafter.
