Academia in the humanities field is particularly calcified and corrupt because it's so hard to measure the quality of the output (or even if anyone wants it at all).
At least with things like maths or computer science research can be verified and has utility to the broader world.
On the other hand, the claim that the humanities are not "practical" has become virtually a tautology, because "practical" has become almost a synonym for "scientific". Nowadays, people don't seem to think that work on love or ethics or aesthetics has practical value. I am not sure why, since actual human lives are intimately concerned with these topics.
