Yeah really don't see what all the fuss is about.... take out a loan, don't pay it back for 25 years (staggered i.e. paying back much less in the earlier years when the debt is at it's biggest), end up paying double what you borrowed - well no **** Sherlock, same principle as pretty much any other loan then.
What I'd find more galling would be if anyone had the bare-faced cheek to suggest that people should be able to borrow £39 grand over such a long period, earn loads of cash and NOT be paying back a significantly increased amount.
edit: I mean for chrissakes, if you look at the spreadsheet for the 25year/£83k example, the person will have earnt OVER ONE POINT EIGHT MILLION! to date in order to have paid back that £83k, they will literally be laughing all the way to the bank (yes, I know that a £142k/year salary won't look so flash in 25 years time, but the point is that relative to the total amount of debt repaid, their earnings are pretty huge. It's all well and good saying ZOMG ZOMG £83k repaid on £39k but that £83k is less than a year's NET (not gross) wage by the time they hit that mark. And yes, some of that £83k will have been repaid in earlier years, meaning it is worth more in real terms, but by that logic, the £39k they borrowed in the first place was worth a lot more in real terms as well.
I dunno, the way I read this situation is that students seem to have a much greater chance of getting some debt written off, what with a £21k threshold, low rate of repayment, being allowed to borrow a lot more money etc etc. Under the old system with £15k threshold to still have debt left after 25 years you'd have to be earning a fairly low salary over that period, whereas this new system is basically saying "here's a big wad of cash, don't worry about it, either some of it will get written off, or you'll be earning so much cash that it will have been worth it".
