Back when I was in school in the early naughties, it was a given that, if you were a humanities student, your tuition largely subsidized the STEM students, because your degree required virtually no specialized equipment, just a building, a professor, and some administrative overhead.
STEM students required all sorts of wild equipment, some so specialized and sensitive that the buildings had to have extra protections built in so they weren't bothered by vibration or electromagnetic interference from nearby lightrail trains. Their tuition wouldn't cover that.
Of course, the school also splurged on pointless real estate expansions, a relatively empty, but massive, student "union" building, intense administrative overhead, sports stadiums paid for by adding on hundreds to student fees (which of course weren't part of tuition, but you had to pay them anyway), and so forth.
If you're a humanities student, you get the short end of the stick from many different directions- paying more than your education costs to support others, for a degree that will earn substantially less than others, which likely has fewer industries that specifically require your degree (putting you in more competition for said jobs against students with other similar degrees).
