It's a complex issue though because although I agree that we need to look carefully at what education is offering us right now (education in a subject versus huge debts when we leave) my own experience contradicts what has already been said on this thread:
My partner acheived a D and an E at A-level and says he should never have been allowed to go to uni, but he did - got a degree and got a good, well paid job.
I was a bright student, got some reasonable A-levels and also did a degree at the same uni. Since then I have done 2 postgrad degrees on top. But I earn peanuts and have trouble climbing the greasy pole.
I would argue that class background plays a more significant part than we would like to admit - my partner is from a more middle class, professional background, had the confidence in his ability, and is also male - and has become a senior manager. I come from a lower working class background, had no confidence, and was constantly offered admin and secretarial work - I am female.
So it isn't just about ability, A-level grades and experience, there is a lot more at work - class, gender, ability, confidence, practica skills, application...
Given the choice gain I doubt I would go to uni especially with the amount of debt it accrues.
Do I think unis mis-sell their courses? Possibly, yes. I think that will change now students pay so much for them - they will become the consumer and if unis don't deliver what they say they will, there will be complaints.
