The best cost control method is to make all public colleges free...that will force private institutions to lower their rates to be more competitive with the free option offered by the State.
I don't care if a billionaire's kid goes to free public colleges. Like they would even go to one anyway. And if a billionaire's kid went to public college, they'd get a great crash-course in what life is like for kids whose parents aren't incredibly wealthy. But really, what billionaire or millionaire would send their kid to public school? They already don't, largely.
