So I’m 20 and I’ve started looking at the salaries of jobs/careers, and this is the impression I’ve gotten. Like that you could spend years cramming a ton of knowledge about a very niche field, and still only get 2-3x what a run-of-the-mill job makes. Is this true? If yes then I guess this route to wealth would only make sense (due to the diminishing returns) if the topic truly spoke to you, right? Are there alternative career paths to good pay than being really good at something really specific?
Trades. If you are a plumber or an auto mechanic you can make a killing. Doubly so if you own the business. If I had it to do over again I would get a business degree and then become an electrician.
