Yeah, on the DC side, I was honestly surprised how Bruce Wayne really isn't that wealthy financially speaking across many writers and titles. He owns a controlling share in a company that sells weapons / pharma / technology / financial / really anything the writer thinks is important to the story. And he has long term generational wealth. So the impression is that he can afford anything, but there's a point where fictional rich characters are able to do things normal rich people couldn't - buy an island, create an army of mercenaries or robots, donate or provide the majority of funding to a charity that is world renowned, pay your way to the presidency, be called a philanthropist playboy bachelor billionaire, build spaceships, etc.
