I dont have any faith that the old groups such as the Outfit will ever make a huge come back mainly because by now the government already took over their rackets, meaning gambling is almost legalized everywhere, the protection racket was simply replaced by legalized security firms which most have connections to high profile politicians or their bodyguards, the banks are giving away any kind of deals just to make you a debtor for life so there goes loan sharking, and also drugs are becoming quite debatable, reagarding legalization, almost everywhere around the world. The only things which will remain are the extortion racket and semi-legit businesses with the help of coruption and of course the old time rackets such as burglary, robbery and murder.
