I think you'll still see 5 mob families in New York but, with the ongoing attrition in terms of both quantity and quality,they'll be smaller, less organized, and less disciplined. By that time, you won't have any guys that were made before the 1970's at the absolute earliest. Most of them long after that. Law enforcement pressure may ebb and flow but attrition is constant.

They'll still have bookmaking and loansharking (though possible future legalized sports betting could cut into that). Guys will still be able to make money with drugs, robberies, or some scam. It wouldn't surprise me if their labor racketeering activities are restricted to construction at that point.
