If you wanted to create a law to fix high education costs, it would be pretty simple.
Limit university endowments to 1 billion. That's more than enough to handle any future research or education projects that would sustain the institution. Once they are over $1 billion, they are forced to either re-invest the funds in scholarships or subsidized tuition, or it gets taxed heavily and those funds are used to subsidize tuition for low income applicants across all institutions. Call it a luxury tax if you will.
Good article on this in the Washington Post for those intrigued.
