(DC) Why don't batmans superpowered friends help with Gotham?

Gotham is routinely described as a hell hole, running rampant with insane meta humans, organised crime and corrupt cops; batman seems to be the only one keeping any semblance of order in the place. So my question is this- why do none of The Bats superhero friends come into help? Surely superman, Wonder Woman or the Martian man hunter could swoop in and clean up the city in the better part of a day?

Baghdad was a hell hole, surely the overwhelming military presence of the United States would restore peace and calm, right?

Nope. Corruption is a disease worse than cancer. At least with cancer you can cut one bit out and hopefully save the body. With corruption that's what the body needs just to survive. In our world Marion Barry, the mayor of D.C., was caught on camera *smoking crack*, severed jail time and still managed to be re-elected. 

So let's say Supes, Wonder Woman, et. al. sweep in and, against their principles, kill everyone in power up to and including the Joker, Mayor Hady. etc. All they leave is a power vacuum that gets filled by the next-in-lines. So now you have Harley Quinn, Hady's Lt. Gov. and so forth. 

Gotham is a cesspool. The people who live there are fish and this is the water in which they swim.
