I'd say Batman is comparable to Bush, in a way, looking at it from my angle.
Batman, in essence, protects interests. He seemingly does it for vengeance or for what he think is right but he'd capture, beat up, and arrest a petty bank robber who'd steal, lets say, 50 grand yet won't, if anything, rarely, do anything to and about white collar criminals, (even with all the super advanced tech he has) whom do more way, way damage to the general public. Case in point: what's going on now. (bailouts) No one wanted to correctly supervise and regulate the system cause of interests now look at what we're facing. I doubt a petty bank robber would cause this much turmoil. (Go after the little guy and use him as a scapegoat) Sounds like iraq in a small way.
For every Ken Lay or AIG that fails how many Petty penny criminals (compared to the mammoths) get overvilified, viciously pursued, caught, arrested, tried, and convicted. An great number, i assume. Not saying let them get away with it, but get the people on the top, just as much, as well. (whom do more damage)
