It's nowhere near the powerhouse it used to be, not even close. But it's far from over. The NY families are the only ones that can be considered large criminal enterprises. The Chicago, New England, New Jersey and Philly families on the other hand seem to have already developped into smaller locally operating gangs that can wield a fair amount of power in their respective areas, but at the end of the day don't differ all that much from a more sophisticated street or outlaw motorcycle gang. The mob in this smaller form will still exist for years to come.
