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 don’t think there’s a strong relation between knowledge and salary. It’s more likely demand and supply - if specific skills are in demand, and not many people have them, then pay will increase. And at the highest levels it’s often not what you know, but who you know that matters.
