just to make all art history courses in the US artificially limit the number of students they take in to match the actual demand.

Why? Surely part of the 'charm' of University is to get chance to study thing you know nothing about just to see if that happens to be your thing, plus studying things just because you enjoy it.

Sure we probably shouldn't encourage too many people to get art history degrees, but why not let people take some art history courses just because they find the topic fascinating?
