At that point, the incentives of schools and the incentives of students would be aligned. Schools would not lend huge sums to students unless they had confidence that the education those students got was adequate to prepare them to repay. And the situation would fix itself. The fixed situation would probably have a lot fewer humanities students, and those students would have better job prospects since supply and demand would be aligned. Degrees would be shorter and less expensive, and overheads would be lower.
