If someone wants to pay money to spend four years of their life studying Gender Studies or Semiotics then good luck to 'em, but make sure they're paying the full cost of their degree, preferably up-front. Underwater basket-weaving is a fine hobby for the idle rich.
I they want any aspect of their education subsidized, they should be studying something both useful and hard. Every university degree should include serious mathematical content.
What about the students who aren't good at mathematics? They're probably not benefiting from a university education anyway. Let 'em go get the low-level white-collar drudge jobs that they'd wind up in after graduation anyway, and let 'em do it at the age of eighteen and start building up some wealth rather than forcing 'em to wait 'til they're 22 with a net worth in the negative six figures.
This, of course, will never happen. But it's nice to think about.
