In the 1920s, there were a diverse array of ethnic organized crime syndicates in the United States. But for most of the 20th Century, it has been the Italian mob, the Mafia, which has dominated, with their erstwhile competitors reduced to footnotes, to the point that, as it declined, many of the syndicates of other ethnicities that have been taking its place are referred to by the name "Mafia".
The challenge therefore, is to either A: figure out how another ethnic crime syndicate could instead become dominant, or B: figure out how no single ethnic crime syndicate could become dominant.
