It's… complicated.

The thing about Batman (well, Batman in the last few decades, anyway) is that fundamentally, he's broken inside. It was low-level crime that took his parents away from him, so he feels the need to fight against low-level crime the most. Oh, sure, he has his own rogues gallery that he has to fight because the police can't handle it, but it's the common criminal, from the two-bit robber to the local mob boss that he has sworn vengeance against.

What a lot of people keep forgetting, though, is that Batman, as Bruce Wayne, does donate much of his wealth regularly to nearly every charity hosted in Gotham, including projects for the poor. But for some reason, everyone keeps forgetting about that no matter how many times he does it. It's a little bit frustrating. I think they just want to sound smart by claiming he could say more lives by stop being Batman, but given that if Batman didn't exist, the city would probably be destroyed several times over, that argument becomes laughable in a world that already fantastic to begin with.

TLDR: Batman's universe doesn't play by reality's rules, numbskulls.

There´s also the fact that, at least in some of the comic books and tv shows, he basically funds shit like the Justice League on his own. If Jeff Bezos singlehandedly funded a organization that regularly stopped intergalactic overlords from taking over the universe, I would be at least somewhat more kind towards him. And yeah, him being kind of fundamentally broken is a key aspect of most of his portrayals. Even a lot of the more serious Animated shows get this.

Honestly, and I say this as a pretty hardcore leftists, but most of the "Bruce Wayne is bad because he has money" arguments seem to have been made by people that probably only watched a few episodes of the Adam West show and read maybe one comic. I would also say it's part of the inherent problem of doing a darker version of a character meant for children, but again even some of the animated shows (which I know aren't just for children) still manage to capture the fact that he is kind of a fundamentally broken person.

I do think these arguments hold somewhat more water when it comes to Tony Stark, even if like Batman his money is the sole reason half of the universe isn't dead, but at least the Marvel movies generally have a tone that makes it pretty easy to ignore such things. Comic book Tony Stark is something else, but even the writers seem to have realized they fucked up pretty severely after Civil War.
