The time bomb I've been idly wondering about (and I don't think anyone is really talking about) is the student loan debt that's building up and will never, ever, be repaid. Post-2012 loans are around an average of £50,000 (my pre-2012 loan was about half that for comparison) and repayments are only taken once you're earning above £25,000 (pre-tax) and then the repayment is 9% of your earnings above that level. So if you're earning £40,000 (which is well above the average salary) you'll repay £112 per month. So that £50,000 loan will take around about 37 years to pay off. Considering post-2012 loans are written off thirty years after they first became liable to be repaid this feels like a small problem. Especially when you consider there are not an inconsiderable number of graduates who are earning less (often much less) than £40,000...
