We all know why tuition have gone up. Because administrative costs went up.This is an inertial thing. Most degrees were all worth something, but with a ton of people graduating with all these degrees, that led to the devaluation of some of them.
But this doesn't address that college costs have gone through the roof, especially public college.

1990 - $2,000
2000 - $4,000
2008 - $8,000
2020 - $11,000
Inflation since 1990 is about 2x. So college prices went up 550% compared to inflation's 200% increase. Public funding of college has dropped.
Just because we all know that doesn't make it so--school budgets have increased only slightly over inflation. The big difference is how much of that comes from the students rather than the government.
