I fail to see how any teenagers will EVER be able to live in their own house and have holidays / a nice life with debts like these. Companies don't pay enough for hard working families to survive with debts anymore in the UK.
Look at it this way.
You have a debt of £10,000 before you even start work. Your house (by the time you come to buy it) will need a mortgage of £150,000. Bills,food, holidays etc will not be as cheap as they are now (but wages will stay static in most professions)
So you borrow off mum and dad to get your deposit & struggle, for say 15-20 years to get your head above water with your wife and you working all the time with holidays every 3 or 4 years if you are lucky.
Now you are 35 / 40 years old with 2 kids. You are just breaking even now - but still can't afford any luxuries or anything that makes you happy as a family. And God forbid you or the wife loose you job.
10 years pass, your kids are in the same cycle, at Uni with an even bigger loan - and they come to you for help (maybe even help for a car or deposit for a house) - You have no savings - you still have a mortgage, and it's another 25 years of working before you can even dream of retiring (with no pension)
Whats gonna happen now ? In 30 years you will just about manage to pay off your mortgage, but you will still have to work be able to afford things. So you will probably die at work, not being able to give your kids any help with stuff.
And this is assuming you don't loose your job, don't get sick, and don't seperate from your wife or have to pay maintenance for any kids you had with other partners or exs(almost everyone will go through a period where they will experience one if not all of these)
And the best about it is, the vast majority of Uni leavers think they can just jump into jobs paying 30 or 40 thousand a year, so they can pay it all off instantly. The reality in the UK is that most Uni leavers start on less than £20,000 (if they are lucky enough to actually get a job)

Nice thought isn't it ....
