I gotta say, just going off seizures and assets forfeitures, these estimates seem a little low, although I will say I suspected the Naples clans earnings were bigger than the he Cosa Nostra, based off fashion and drugs...
Those assets seized represent wealth amassed over time. The figures quoted represent annual turnover. And I find them more believable than the astronomical figures we see. And that goes for the Italian Mafia as well as other OC groups.
