There's a clip from The Batman ( the animated show) I can't find at the moment, but it basically involves Batman clearing a room of thugs by offering them jobs. They all walk out, without a punch thrown.
In the real world, no one that has Bruce Wayne's degree of wealth is a truly positive influence on the world on the whole. There are no ethical billionaires.

He is always shown in stark contrast with the likes of Lex Luthor.
