They cannot. It is all wayyy exaggerated into non reality liked I've stated before. Many times.

One example: The estimate of Al Capone earning $100 million, which would be 1 Billion in today's Dollars, was only a guess and it was the GROSS amount of Businss the entire Outfit did in one year.
It's not how much money Al Capone put in his fucking pocket AFTER all expenses and payoffs and everything else. If Capone personally earned 5 million I would be surprised.
Then, he had to reinvest a lot of it into the business again. When he went to prison for good, THE OUTFIT took it over, not his fucking wife or children.

You can always figure that whatever exaggerated number is named by someone, they don't know what they're talking about and you can usually make it on an average 10 TIMES LESS and then you will be closer to reality.

The Outfit guys would LAUGH at some of the old estimates made by people, especially the one about Al Capone. The estimate made it sound like Al Capone personally put $100 million Dollars in his pocket and of course his family would probably eventually inherit most of it. Double LOL,LOL.
