[Marvel] How do mobs still exist in New York?

616 only please.  With superheroes operating like Daredevil and Spider-Man, they seem to take down a mob boss every other week.  I live in New York and I'm pretty sure there aren't that many mafiosos in the city that 40 mobs could be busted up per year and the city would still have to deal with them.  

Add in the Punisher who kills entire gangs?  How fast are they springing up?  Punisher must have killed thousands of people so far, he mows down entire rooms.

Because the mobsters provide services/products that a lot of people want and can't get through any other channel.  Thus they are willing to give mobsters a LOT of money for those services/products.

And because no matter how many mobsters get taken down, there's always going to be someone new who wants that money and think they can "beat the odds" with vigilantes.

In other words, all the superheroes aren't stopping crime, they're creating job openings.
