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. But within the context of the DC Universe, Bruce has been routinely demonstrated as using his wealth in the most socially conscious, progressive, and generous ways. He is always shown in stark contrast with the likes of Lex Luthor.
