There are plenty of mob guys from smaller families who have a boatload of money...less competition from other families and demand a bigger share of the profits because they are the only game in town. John Scalish from Cleveland was said to be worth upwards of $200 million when he died. Scalish had the Vegas skim money coming in every month. Russell Bufalino had it all to himself up in Scranton, no kids, didn't live an extravagant lifestyle. Gabriel Mannarino and John LaRocca from Pittsburgh were both said to be worth over $150 million when they died, most of the money coming from the Sans Souci Cuban Casino back in the 1950's and a lot of gun running to Cuban Nationals during the late 1950's and early 1960's. I personally think it is hard to determine the net worth of a mob figure, unless they had a legitimate business portfolio. Paul Castellano was extremely wealthy, had many legitimate corporations, and came from money back in the old country.
