The government incredibly expected £9000 a year tuition fees to be the exception rather than the norm. As government has to fund the tuition fee loans, it can't actually afford to do so with so many universities charging £8.5-9k, and the government doesn't even start to get repaid until three years after they are introduced. The government have made a big song and dance about how this system is fairer because you don't start paying the loan back until you earn a higher income than in the current system. However as you have to pay back more, you'll be paying it back for longer and there are reasonable scenarios where the value of the loan is never paid back. Quite simply the sums don't add up, the plan is not realistic and it's a reasonable assumption that it will be changed to the detriment of students a few years after its introduction.
