If Batman was real today, he'd go after the CEOs of companies, not gangsters.

Yes. Not one really questions why Gotham has such a high crime rate, but where there's poverty there's crime. I think we need a working man's batman.

Someone whose super power isn't having infinite resources.

That's the internet pop-psychologist interpretation, but the people actually writing him often have him doing his best to better the Gotham around him. A lot of the petty thugs he catches are given chances to redeem themselves via Wayne based welfare programs.

The former richest man in the world gave away much of his fortune and continues to do so. https://en.wikipedia.org/wiki/Warren_Buffett#Wealth_and_philanthropy

Bruce Wayne is not like that at all though. He's in a position where he could actually do something about the problems of Gotham City and decides to go LARPing instead.

To be fair, he beats up a bunch of rich criminals too but he whole thing is really more about his ego than about doing good.
