You make more within the same field often times with an advanced degree but a lot of things (business owner, engineer, etc) don’t really require advanced degrees and can often times pay extremely well.

Like take tech. If you’re a good software engineer and you don’t work in research, having a graduate degree is kinda pointless. You’re not going to be a better engineer for it. Yet you can make a lot of money with just a bachelors and sometimes not even a degree. It’s all contextual.
