A degree needn't cost what dreaming is suggesting. However, for students at Russell Group unis and most of the "old" unis it will.
Students are objecting because the interest rate on their loans will increase and the time before the loan is written off will increase from 25 years to 30 years, in addition to the almost tripling of the fees themselves. Most students will need to take out a loan of over £40k and will need to earn about £43k just to cover the interest, which will begin to accrue from the moment it is taken out. Even accounting for wage inflation, many students will never repay the loan, so will have a debt around their necks for 30 years.
They are also protesting because the guaranteed bursaries to students from families earning less than £25k are being abolished.
The mega-rich will be able to pay the fees upfront, so avoiding years of debt.
The government's agenda seems to produce a system not unlike in America, where the Ivy League unis can only be afforded by the stinking rich, while lesser mortals go to the much cheaper and less prestigious state unis. You only have to look at government (and opposition) front benches to realise that attending a prestigious uni is the key to power.
This all needs to be put in the context of rising unemployment, cuts in public services, the abolition of EMA and very little chance of affording a mortgage. Many of the young people I know have a bleak outlook on the future.
