In your experience, who makes the most money in the industry?

So obviously at the highest level, the star directors and producers make the most. But for the rest of you that work in the industry, who would you say makes the most out of the people you know? Is it DPs? Directors? Producers? Does it depend which area you work in like indies, commercials, music videos etc? Also, is it difficult to find consistent work just as a producer or director? I’m asking because I’ve heard the advice of learning a technical skill such as lighting or editing if you actually want to work all the time.

Edit: I know money isn’t everything and some of you may say something like “If you want to make money then run from the industry” lol, but it is a concern of mine especially with the state of the industry these days. Thanks!
