CEOs of companies existed in 1939, and did before. 1939 would have been the time of the great depression, World War 2, fascism, and Batman didn't go after them, he went after the people who needed work and took the last chance they had.
Bruce Wayne is just a form of Bill Gates. Donates millions to charity, good causes, hospitals, fighting diseases, but he still has lots of more money than when he did before all this "charity". The difference is that Gates doesn't put on a mask and go punch the poor of Seattle.
If Batman was real, he'd be a dickhead, worse than Musk or Bezos.
EDIT: Why mine and no one elses? This dude is annoying.
