When I was in grad school, approx the Pleistocene Era or thereabouts, whenever I was carrying around some book that had not been assigned in any course, I would be asked, "what's that for?" In our History of Thought course, Dudley Dillard (actually a very sweet guy) would ask things like, "What is the Marxist concept of capital?", I would say, "a social relation," and people thought I was some kind of Marxist rocket scientist.
A committee of American Economic ASsn members, I think it was a formal committee of some kind, recently issued some kind of statement of concern that econ grad departments were producing cohorts of idiot savants who could manipulate equations but had no clue about anything else.
