There maybe a sort of monopoly here but monopolies never set their prices to free (unless they're trying to destroy competitors which is obvious not the case here) There may indeed be grotesque stratification problems with the system but that doesn't mean some part may do the right thing occasionally. Frequently even monopolies moderate their behavior out of fear of regulation. Here perhaps schools fear the reputation hit of graduating too high a percentage of rich dimwits.
