Why not? First of all, you are kind of forcing people to do one kind of thing in order to survive. Yes, it’s true that lots of people are not capable of advancing art or physics. But what is also true, and more important, is that most people dont want to do that stuff. Forcing everyone to be an “intellectual” for their survival would be downright dystopian. Second, it wouldn’t produce good results anyway. There would be a flood of bad and incorrect intellectual works. We would see problems arise similar to the ones we see now like the reproducibility crisis and the social justice double-think on campuses. When college becomes a right instead of an exclusive privilege for the intellectually gifted, it no longer serves the purpose of intellectual advancement.
