What is obvious and what would be hugely socially useful would be to have a completely online, completely free accredited option for degrees that don't need labs. That would cause downward pressure on all of tuition outside the top universities.
The price of college at this point is a ridiculous value proposition to the average student. Who cares about the top students and the most gifted people. They will be fine regardless. The average student is getting crushed and ripped off blind.
Ripping off entire generations of young people is really stupid and is going to have devastating long run social consequences.
