Quite a few undergrads come in thinking they've discovered the One True Path and of course it's—sigh—one myopic brand of libertarianism or another. Social science professors get pretty sick of that shit and I'm sure some of those students take the irritated rejection of their tired failing-to-engage-with-the-material crap as "Marxist professors pushing their ideology" but for the professors it's like if physics professors had to deal with every incoming freshman class having a few kids per hundred who are dead certain they've discovered the secret to perpetual motion, are in fact basically experts on it, and are very resistant to learning that they may not have the full picture.

They'd probably also try to temper the enthusiastic incorrectness of freshman coming in as full-on 1930s-throwback "Stalin was awesome, actually" tankies, but there just aren't that many of those. The confidently-wrong freshmen tend to all fit a similar mold, and it's not leftist.

Do economics programs ever push a single theory? They're supposed to teach you about the whole field, no?

Economics stands apart from other social sciences in its culture. It has pivoted quite heavily when it was transformed from political economy into economics during the marginal revolution. And while Marx can be jokingly referred as "a minor post-Ricardian" by some economists, he is considered a father of sociology alongside Comte, Weber, Durkheim and Spencer.

We're not talking about an economics program - that would not likely have a Marxist professor - but rather a history class, which could easily have one.

Or how many programs in general push Marxist theories in the US.
