Even if they did raise the fees... So what? Unless the repayment rate increased too, the cost of university tuition fees (your maintenance/grant is a personal matter) are repaid at such a low rate and then scrapped after so many years. The only difference is that more people would be unable to repay it in full.
9% of an income greater than £21k is really not a lot. The fees could be £100,000 a year and you'd still be paying back around £30 a month on an average graduate income. They would just end up being scrapped after 30 years of repayments anyway.
While there should be a lot more support for funding the students (the loans system can be a little bit presumptive about how much input there is from parents), the fees are really not a major issue. It's the repayment rate which gets you, and it's not even that bad. A lot of people are unnecessarily worrying about the fees.
