[DC] Why do people stay in Gotham City when it's a living hellhole?

First you have a psychotic clown spraying laughing gas everywhere while setting the police station on fire, a Mob boss who flips a coin to determine if he shoots you, a Mexican wrestler who's addicted to Energy drinks and Steroids, a living plant lady who will turn you into fertilizer.

And the local prison seems underfunded as the criminals escape on a weekly basis.

Oh and to top it off you have a deranged man who dresses up as a bat driving a armored car smashing though infrastructure and no regards for traffic laws.

So why don't people just pack up and move to a safer city that isn't under daily threat of being blown up?

Various sources make Gotham less hellish than depicted. Writers for years asked he same question, if "Gotham is so bad" why don't people leave. In reality Gotham is a metropolitan city thus has it's good and bad areas. Batman and the Family pertain to the bad. More recent showcase Gotham with industry/business but namely Culture of fine arts. 

Plus,  Gotham tends toward regular old-fashioned crime; mobsters, thieves, and  
 the like, things common in Many cities. If you go to a place like Metropolis, you have a skyscraper a week getting damaged or huge destruction from the things Superman fights. Coast City once got completely destroyed.   
Keystone City has a horde of super-powered villains running amok. 

Central City has Flash's rogue gallery

Star City got destroyed by an artificial earthquake and replaced with an enchanted forest. Gotham's really not that bad, all things considered.
