Also, who are you to tell someone that they can't go to a school if they can find someone to lend them the money to do it?
If you're in the US and you don't think that rate is unreasonable, I'm curious as to why. We're talking about loans that cannot even be discharged in bankruptcy, in a 0% interest rate environment.
But I'm paying roughly the same for loans taken out in the last five years. It's irritating.
That part is also a zero-sum game, because all parents work harder to afford the best neighborhoods and that makes the price of living in those neighborhoods go up, leaving everyone right where they started only they now work two jobs instead of one.
Decoupling property tax from school funding can help with that. In Universities, a system that is free but only accepts the people with the best grades, IQ, or some arbitrary qualification can help, but brings its own problems.
My best investments are the raises I get when paying off my student loans ahead of schedule.
