The Genovese and Chicago Families are the 2 most secretive, united, cunning, disiplined, Wiley and circumspect families from day 1.
Both have never had a attention seeking boss like gotti,both have greatly benefited from leadership that happens to be wealthy and in most cases don't want to be bosses but take the position because it's the best thing for the family. The families were the first to present facade heriarchys and upfront bosses to insulate the leadership from law enforcement scrutiny and it's something they have done for many, many years. Its no couincedence that both of these families most important turncoats we're soldiers(barone and Calabrese ) because no one above capo has ever flipped for these families.
The leaders for the most part are older and the links between the families is very real. QD Cirillo is very close to Chicago and Matassa Jr and Danny Pagano speak regularly as they are brother in laws and also both of them are Capos.
