In general, I’m opposed to the idea. College professors don’t work for free, and colleges have to pay them.
Professors don’t make up near as much of the bill as the administrators and coaches that pull down 7-figure salaries. There’s almost as much bloat in the US University system as in US Healthcare. The answer to both is the same: they should ideally be free. Failing that, it should be illegal for either to be profitable businesses.
