Its not just about paying back fees, its about British society and where we want to go with it.
Many students in the next few years may not be able to study near home to cut down on bills as its expected by the government that several Universities will go bankrupt. The government intends this to happen and is supportive of them going to the wall and shutting down. At least 3 are already on the list of 'won't last long', before the fees competition truly starts.
Universities will probably break into 2 fee charging groups - those who go for £6000 and those who go for £9000. It is very likely that any institution who charges the lower fee will be seen as 2nd rate and so will its graduates. Therefore as many as possible will try to charge £9000, which is in theory 'exceptional' but in reality is going to happen in a lot of places unless they want to loose all status and respect.
Some University colleges are already speculating on breaking away from government control (I cant remember if the first one to suggest this was at Oxford or Cambridge). This will essentially make them fully private and as such they will have NO restrictions on fee charges whatsoever. So, the elite, also known as the very rich, could (in theory) have to pay £20,000+ per year (or whatever fee makes the college special enough) to go to somewhere 'exclusive'. It will also mean there will be no requirement to take any poor people at all, nor will any other critera be set by the govenment for private establishments which once would have aimed for some attempt at equality.
Already 1 private 'University' specialising in law (as far as I know, never part of the state system) is expanding into other sites in the UK, probably as a result of the change to fees.
Its not just about paying fees - its about who Britain will become, about class and wealth, probable access only to the very rich at certain institutions, re-starting a system of snobbery and 'Ivy league' atmosphere, privatising Universities so that the nation has no control over who attends them or how exclusive they become.
Its the sneaking underhand privatisation of the education system that many people will not realise until its too late and the results of that choice for snobbery, elitism, employment prospects and running the working classes into massive debt. And debt is an excellent way to control people.
