Schools bear a lot of responsibility but then we can't ignore the role state governments have played by drastically slashing funding over the past 10+ years. Probably only going to get cut further in the COVID environment.
Purdue University hasn't raised tuition in something like 5+ years and is also still affordable. It's not Ivy league by any means but it's a great school. You need government and administrators/boards willing to support this though, 99% won't
Something external needs to happen to stop rapid rise in tuition. Maybe it will be COVID. Maybe state governments will reign in the profligate spending of their universities. They aren't going to do it themselves (at least top Universities, schools at the bottom of the food chain could definitely go bankrupt.)
