to sum it all up: you had to rule chicago or nyc to rule american crime . . . iowa? not so much
germans got to that game too late to fully organize and become a lasting entity, especially in large, wealth-generating cities.
The Lebanese ('Syrians') were successful in St. Louis and were on an equal footing with the stl family here until it all blew up (literally) in the 1980s. I don't think that they had a presence in Chicago or NYC.
Also, the blacks have been here a long time and many of them are still active in gang activity/OC.
As far as germans go, I don't know about the states, but I wouldn't be surprised if there were some type of german cybercrime rings. Many of them seem to be actively involved in hacking.
