Electorates in almost every state have put people in office who have been hacking away at state university budgets. They are saying loudly and clearly, "We do not want to support the public university system. It is a bad use of our dollars." So, what do the universities do? They see that the support from the state is dropping precipitously, so they look for ways to stay solvent.
If you are complaining about this, maybe you are the problem. Americans have asked for their state governments to be slashed. That isn't free. Now state services will be slashed too. The 20 kilobuck annual in-state tuition will be a reality by the end of the decade. No one seems to care about that. So grow up and live with your choices.
