Something about Bruce Wayne, a billionaire, beating up petty criminals who likely turned to crime because of billionaires taking all the money, but also leaving villains like the Joker alive to commit more crimes...
The main problem is Bats doesn't realize that Bruce Wayne is the one who can actually make the societal change he wants with all of his connections and resources.
Batman would be a better story if Bats were poor because you wouldn't be constantly asking if he could use his resources on something more important than a jet powered car.
