We tell parents a degree is the safe investment in a child. The numbers now call it a bet.

Ask most parents what school is building towards and, past a certain age, the answer is a degree. It is the biggest single investment many families make in a child, close to thirty thousand pounds in tuition before a penny of living costs, and we sell it as the safe one. The safe part is the bit the numbers have quietly stopped supporting.

Start with the return. The Institute for Fiscal Studies, in work for the Department for Education published in June, put the lifetime gain from a degree at about a hundred and nine thousand pounds for men and ninety thousand for women, after tax and student loans. That is a real sum. It is also a good deal less than the same body estimated a few years ago, and the direction is the point. The extra a young graduate earns over a non-graduate, for the twenty-one to thirty age group, has fallen by roughly a third since 2007. Strip out inflation and graduate pay for that age group has gone backwards.

Then the spread. The average hides a widening gap. The IFS reckons about a quarter of graduates end up financially worse off for having gone, once the debt and the years out of work are counted, and for men who arrived with weaker GCSEs that figure climbs towards forty per cent. The subject and the university matter enormously. A degree is no longer one product at one price. It is thousands of products, some superb value, some that leave the buyer poorer, sold under a single reassuring label.

Meanwhile the price went up and the seller is in trouble. Tuition in England rose to nine thousand five hundred and thirty-five pounds this year, the first increase since 2017, and is set for nine thousand seven hundred and ninety next. And the Office for Students has reported that close to half of England's universities were heading into deficit. You can hold two facts at once: fees rising, and the institutions charging them still losing money. That is a sector under real strain, passing more of the cost to families, for a return that is thinning.

None of this is the whole story, and the case for the defence is real. Universities UK point out, fairly, that the premium is holding up for the large majority, that a graduate is still far more likely to be in skilled work, and that some of the lowest-earning graduates do jobs a society most needs. On the averages, university still pays. If your child has the grades and the course leads somewhere real, it very probably remains the right call.

But it pays on average and it is a safe investment are two different claims, and we have been making the second while only the first is true. An investment you would call safe is one where the outcomes bunch together and the floor is solid. This one now has a long tail of people who lose. The honest thing to tell a sixteen-year-old is not get the degree, and not skip it. It is that this is a real decision with a real chance of not paying off, and it deserves the scrutiny of one, not the autopilot of a default. The machine did not cause all of this. But by making the graduate skill cheaper, it leans on exactly the end of things where the returns were already sliding.
