Sicilians do a much better job at running American Mafia families. Look at the Rizzuto Clan, all ran by Sicilians. Look at the Gambinos, it's the Sicilians who are repairing the damage done by John Gotti. Also look at Detroit, ran by Sicilians and still an underworld force. Look at the Bonannos, Joseph Massino basically tried to purge the Sicilians out of the family feeling like they were a threat and look what happened to them, though they still have a Sicilian faction. The future isn't in America anymore, the recruitment pool is of very low quality and it's only going to get worse.
