Ha, you're right. Economics is an exception. I minored in economics, and found it amusing that professors who expounded on the virtues of capitalism were doing so within an socialist institution.
However, looking back, I'd probably place most of my economics professors in the neoliberal camp. I'd propose that the left/right divide is primarily about nationalism vs globalism now -- my professors would have tended to support international capitalism rather than national capitalism.
Figures like Mises weren't mentioned in my classes, despite his famous prediction that the economic calculation problem would cause the fall of communism. Yet Keynes was discussed thoroughly.
Nearly all of them, having majored in Economics.
