isn't a big part of the whole setup that this would not help much? like Gotham is just too corrupt, whenever programs are set up to invest in the public, they're mostly just stolen from.
Wayne is a philanthropist who gives a ton of money back through his own programs, right? presumably better overseen than the government ones.
I don't know how much money of Wayne's is actually used for philanthropy, but he can't just give the city all his wealth because it's too corrupt for it to be used well, right?
