When a typical student finishes their university degree (4 years) they will be in a £50,000 debt. This means that to begin your career, you have a huge debt to pay off. Now obviously you are not expected to pay it all back in one go, but it's still bad to be in debt as soon as you get a job. And remember that jobs are becoming harder to find and as a result most people will probably never be able to pay off the debt.
There used to be a grant scheme in the UK which basically meant that university was free for everyone and once you finished university, you didn't have any debt to pay back to government. This was brilliant, however it got removed in 1998.
