[Marvel] Why is New York City so violent?

The city is the home for 95% of Marvel characters, yet it's still so violent that it needs the Punisher killing dozens of thousands of criminals throughout the years to keep crime in check.

Why is it so violent? How are 95% of Marvel heroes not able to make it less of a shithole?

Punisher isn't really reducing crime in NY specifically. When he removes criminals, he leaves an opening for
other out of city gangs to move in to take their place. 

So it's not that NY is especially violent, at least not more than any other heavily populated city.
