Hence why the higher fees in the first place is stupid. However it will never reach the trillions of pounds that the bailing out of capital did.
The higher fees aren't stupid, they're necessary, it's the lower limit on paying them back that's an issue.
Currently pretty much all courses at all universities are near the maximum price - that's already beginning to change and will continue to do so along market rules. Once the data are available, those courses that are less likely to result in a good job will have less value in the market and universities will have to charge less for them. That will mean that given their limited resources (space, lecturers, etc) they will have to try and maximize profit from what they have. In that scenario, only specialist universities will offer Fine Art and Sports Science and hopefully none will offer Social Studies. That will also conveniently tie in well with what the job market requires - if the market is short of IT graduates then IT degrees will have a higher value and universities will focus on it more.
These perfectly sensible and appropriate rules are skewed by the fact that there is a lower earnings limit on the payback of these fees. That allows those who want to doss who never plan on earning more than the lower limit (especially those who are willing to drain the state on benefits) can simply use it as a place to get ****ed for 3 years (not that there's anything wrong with enjoying uni, I certainly did my fair share of that).
And whilst bail outs are another discussion, I agree that they were entirely wrong - it should never have been done for many reasons.
