But why should, say, a teacher have to pay back their loan, but someone else who chooses to pursue a career as a potter be able to avoid paying back any fees? Ok, so they might not be a "high" earner during their earning years (which from now on extend till 67, way beyond 30 years post university) but in the final wash up it seems fair that they repay their fees.
Exactly.
Such a bizarre and entitled attitude for someone to rack up tens of 1000s of pounds in student debt for a degree, and then do their best to earn very little, so they never have to pay a PENNY back. WTF is the point?! 
They are basically using public money to get a degree, so they can faff around for 3-4 years in education, and then think they're a cut above because they're got a degree, but they have no intention of giving anything back to society. As I said 'entitled,' and also very selfish.

What about midwives? Most of them will never earn enough to pay back the loans that they have to take out for their degrees that they have to have.
What about nurses? What about teachers? What about social workers? Are they smug folk for not earning enough to pay back their debt?
What on earth are you on about? Most of these professions WILL earn over the threshold, and WILL pay some back.
Nevertheless, I am not talking about midwives and teachers and social workers etc, I am talking about entitled-to, selfish individuals, who take it upon themselves to do a degree, rack up 10s of 1000s of pounds of student debt, then announce proudly and smugly, that they have NO INTENTION of ever paying a penny back.
Disgusting attitude. As I said, there is a flaw in a system that allows this, and it needs sorting to stop this dreadful abuse of the system.
