I would say 100s of millions. He made millions a year from the 1930s to the late 1980s
Chicago was wide open in the 40s and 50s And really till the earl 90s, they owned the city,everything in the city was under they're control,They made billions..... The wiretaps from the 60s showed that Gus Alex and frank strong Ferraro were making 250k a month from sports betting in the loop and half of that was kicked up to "the WESTSIDE ,which was ricca and acardo and giancana and they had 9 capos and all the business ,street tax,strip clubs ,loan sharking ,pornography,restraunts,car dealerships,card games,vending machines, the laborers, the teamsters and the hotel and restraunt employees and I'm talking the heads of the national unions not just all of the locals etc etc. ...your talking about the most disciplined ,ruthless leadership,old school all the way and gangsters, there was no hemming and hawing...you fucked up and you were gone ,complete sticklers for the rules ...everybody kicked up..... In my opinion in terms of stashed cash ... He's the richest gangster of all time. The longevity is what does it ...he was boss 13 years before gambino and 13 years after. The family was his until the day he died in 92...your talking 48 years even at 2.2 million per year that's a 100 million and I'm thinking it was more like 30 million a year
