Guy I knew once was the son of a nuclear physicist. While maybe not quite as smart as his Dad, he was still pretty bright. He started his career as an apprentice plumber. His plumbing career got cut short by a serious back injury so he went back to the books and got himself a degree in mining engineering. Long story short he had a great career in mining and ended up as the wealthy CEO of a listed mining company.

Another guy I know started his career as a cabinetmaker but dropped out of his apprenticeship to go into software development. He didn't have what it takes for that and now he is unemployed.

Moral of these stories? Everything depends on your abilities and interests. Hitting the books and going after a white collar job works well if you're smart. But there a lot of frustrated white collar workers out there doing meaningless work or (with AI at the moment) getting laid off. Many would be better off doing a trade.
