If we look at the evolution of both the American mafia and the Italian mafia(cosa nostra, ndrangheta, Camorra) then we see that the Italians succeeded a lot more over the years while the American mafia is not enjoying nearly the same success and is not making near the amount of money presently. What do you attribute this to? Better law enforcement in the US? Or were the Italians just a more resourceful and smarter over the years after seeing the Americans succeed in the early to mid 20th century?
