Russians do seem to do the sophisticated crimes well like health care fraud but I've never heard or seen them handle much if any gambling or do shy outside their community, no labor / union stuff either . However they do make a ton with the women stuff

I still see the Genovese as being bigger earners than the Russians as their gambling and shy are huge and cover big areas . Plus alot of green and extortion / union / labor . They really are pros at the the quasi illegal / legal stuff .
