When I was at University in the 90s I got a grant which covered rent, bills, books and some left over to live a basic life. Luckily my Mum and Dad helped out and couple with an overdraft lived pretty well. I then did a Masters and got paid(!) £400/month to do it. I came out University education with an overdraft of £3k but a BSc and MSc. I could get a job and comfortably afford a 2up/2down no problem.
The Student Loan thing is an utter scam. It should be scrapped tomorrow and anyone paying it should have the debt cleared. I work with people who have nearly £70k in Student Debts - how can we expect them to buy a house (ha!), save for a pension and live? It's disgraceful. The additional tax on their income means that once/if they get to be higher tax payers any extra income is not far off taxed by 50% - that's wrong.
I've been to plenty of conferences/talks where they say that even degrees/Masters/PhDs in things like medicine, law, accountancy, engineering, software development which were almost guarantees of a good job are also some of the biggest ones at risk from AI which means it's going to get even harder for younger people to do well.
The whole system is a scam. You should be able to learn for learnings sake, not just to make money from it.
