You are right, of course. The poly science, lit, comp, and several economics courses pretty much espouse Marxism. But it is hard to work that type of position into physics, calculus, chemistry, accounting or computer types of classes. That is probably what steered me into more math and science classes even though they weren't my major. It doesn't have to be a magic curriculum, just one where they actually teach hard sciences or skills related to a real job. To many kids haven't been prepared to take these more challenging courses, so they waste their time taking easy clasess like art history, poly sci, sociology, black history, women's studies, literature, where all you have to do is echo back to the professor the limp minded PC drivel they spit out, and you'll do no worse than a 3.0.
You are forgetting environmental "science" and climatology. :)
I realize we're talking college here, but do you know that the intro level science and math courses in many universities, taken by those who are not intending to be science majors, are watered-down dreck ? Take a look at the lower level books used in the universities and you'll see what I mean.
