Carlo Gambino become so powerful because yes,was smart but was sicilian and in the 1950s most of the family boss was sicilian and/or was born and emigrated to america so thanks to this net he can expand the family rackets,a thing that a boss like costello that was calabrian or genovese that,worst, was neapolitan wouldn't do.
Why wouldn’t Genovese or Costello not be able to expand the family rackets because of that? And Costello was northern Calabrese I believe which was closer to campania. Southern Calabria is more like Sicily in dialect and culture I’m assuming. And I would think that both Costello and Genovese had a lot of support from Sicilian mobsters within their crime families in order to become bosses no? My family is from Sicily and I’ve never understood the differences growing up.
