The average owed now is £35-£40k. But I would imagine that those saving for a house would owe the average of £20k or whatever it is[when the fees were £3k and not £9k.
And either they are earning enough to pay begin to pay it back a little at a time, or not earning enough, and indeed as you say, may never pay it back.
But either way, and without meaning to sound harsh, they did have a choice. It was not forced upon them. They knew what the deal was.
And the £3k fees per year were under a Labour government as well as Tory.
I may have got some of my figures a bit out there, but you get my drift.
A government does not parent young people. They themselves and guardians make the choices.
