I think that really depends on the future of law enforcement, which includes social, political and economic variables that we can only guess at. Obviously, the powers of the federal security agencies have grown considerably since 9/11 and RICO remains a formidable tool in the hands of prosecutors. It's not a good time to be on the wrong side of Uncle Sam, and considering how permissive the American public has been in terms of law and order, I don't see that changing.

Still, considering how deeply ingrained the Five Families are in NYC and the sheer amount of prestige associated with the Mafia, even if a bunch of the families stay weak or get weaker, there is ALWAYS going to be some group of goombahs seeking to style themselves as the inheritors of Lucky Luciano. The fact is that the hierarchy, rules and status that come with the Mafia name and organization bring with them certain benefits that a simple crew of criminals don't have on their own. Obviously, those hierarchies and rules are often bent and broken, as we see today, but as long as The Godfather, Goodfellas, John Gotti and everything else about the Mafia -- fact and fiction -- looms large in the public imagination, there will always be people out there trying to profit from it (even if it is more image than substance).
