While I’m certainly opposed to price controls and salary caps in the private sector, perhaps they would be useful in state run, taxpayer funded academia. Cut some of the ridiculous faculty, staff and administrator salaries and adjust tuition downwards. Replace a lot of the university support staff with work study programs and have the students pay for part of their tuition with labor towards running the places.
Another big source of funding for student tuition and other expenses is to tap into the various endowment funds set up by so many, especially larger, colleges and universities. Some of these funds are in the BILLIONS, and tapping into some of these would go far to cover the costs of operations of the schools, thus much reducing the need for tuition hikes, and in many cases, allow a much lower overall cost for college attendance.
