I know a couple, both intelligent, good people, where the wife has a university degree and the husband doesn’t. The husband’s opinion is a university degree teaches you how to think around problems.

Certainly some people are great problem solvers even without university; and some are rubbish even with. But any good degree should help you learn and improve that, besides the specialist knowledge you gain.

So it’s useful, but very much not the be all and end all of human value!
