College should just be cheaper for everyone. Eliminate federal-backed student loans, eliminate useless classes, eliminate remedial classes, utilize more technology, eliminate excess administrators, eliminate ever-expanding resort-style amenities.
Or make them available to everyone irrespective of their income, make sure it covers the entirety of tuition and board cost, subsidise interest, and require repayments after an income threshold. Offer discounts for people that pay upfront. Get rid of "free ride" tuition in its entirety. This is the Australian and UK model.
I agree with the other stuff though: eliminate useless classes, remedial classes, etc. Also 2 years of courses should be allowed to be completed at community colleges and transfer in directly.
There also needs to be more incentive towards vocational work and apprenticeships.
Everything that you mentioned otherwise comes as a result of universities designing for-profit over for-education. Because they have to attract the people with the deepest pockets, which means resort-style amenities. The easiest way to solve this problem is to just make college free and give people the choice of going the traditional route, going to a technical school etc.
If people want to get a college education, they should be able to.
