Ahhh, I dunno what country he’s from but in my country (Canada) there are loads of jobs for math grads. The one thing you have to give up on is pure math. No business is interested in paying someone to write proofs.

I did a major in computational math with a joint pure math. I took a lot of pure math courses and loved them but there’s no practical use for them outside of academia. It’s like learning to write poetry.

However, the skills of a mathematics grad and the broad applicability of mathematics to many areas of business, engineering, and science are undeniable. Even someone who has only studied pure mathematics has a huge advantage over someone who has an unrelated arts degree, for example, all else being equal (personal hygiene, social and communications skills).

All else is rarely equal though. But that’s another matter entirely!
