What about Roy DeMeo in late 70's with the car ring racking in an estimate $150,000 a week. He also brought the Westies in alliance with Gambino family paying 10% of their profits. He also moved allot of Narcotics and also made allot of money in pornography.
DeMeo was a good earner but nowhere near the top. The biggest illegal money came from:
1. bootlegging - Al Capone made $100 million, which is billions in today's money in about 6 years
2. narcotics - The Pizza Connection guys moved billions in heroin over 10 years
3. gas scams - The Colombos, Gambinos and Genovese made hundreds of millions in less than 10 years
4. internet/phone scams - One Gambino crew stole about $650 million over 10 years
All of this is dwarfed by the Colombian and Mexican cartels.
