That's one thing the Mafia can claim over other groups or gangs, history! They go back ages, eons! Latin Kings, Bloods, Crips, La Eme, Gangster Disciples, Vice Lords, most gangs can't claim ancient history. A few other examples are Triads and Yakuza, they go back to ancient times.
Here's the catch, they all are already 50-60+ years old and still be here another 50+ years. So that point is moot.
