Gotham is corrupt on a near supernatural level. No amount of Bruce money is going to fix it. It's infested with the mob, serial killers, manipulative shadow organizations and actual monsters. It's like old Vegas on allllllllll the steroids. The " Batman should use his money instead of beating up the poor muggers and rapists!" Is such a bad take I'm so tired of seeing.
Anyone who actually pays attention to Batman media knows that Bruce does also use his money that way and 90% of the time it's a waste thrown back in his faceand undone right away. The city is sick and shit needs to be ripped out to fix it and Batman is the only one who will do it because the Police are constantly infiltrated by the various crime factions to the point that there are only 3 trustworthy law enforcement officers in the whole thing.
