You're determined that we're also going to debate tuition fees aren't you pottered? 
I'm pretty convinced that tuition fees are putting off kids from lower-middle income families going to university.
And as we all know the working world is becoming increasingly specialised - for lots of careers now a PhD or even post doc experience are necessary: I don't think my DC's careers will properly start until they're in their late 20's. And I fear that it will put students off from staying for their post grad qualifications with the debt hanging over them.
Plus, with the anti-immigration stance this country has taken, we need to develop home grown talent. And that means a lot of young people going to university. And increasing numbers as we get increased automation/AI's taking over traditional blue collar roles. We need more STEM candidates in industry - particularly tech (my current field, so I know that for sure).
Of course, we could fund more university courses for those on lower and middle incomes, and still have a cut off after which kids of high earners paid them. But they're paid by the young person, not their parents, and that doesn't feel particularly fair to me. I'm open to persuasion though, I'm still thinking about it.
I've enjoyed the debate on this thread and that it hasn't got mean (Monaco mix up notwithstanding
) so thanks all. I'll check back tomorrow as have to go to bed now.
