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?
I would certainly recommend picking a field of study and work for more reasons than just the money. As a counter point to your plot, I have seen small career moves result in huge pay increases.
