In 2002 the FBI estimated that the Mafia earns $50–$90 billion a year - This is for the US mob.
That can't possibly be true. I imagine combined net profits for all made guys and associates is probably about $1 billion. That would work out an average annual income for every member and associate of about $100,000 - and that's for a very high end estimate of 10,000 members and associates combined (i.e., 10-15 associates for every made guy). And I wouldn't be surprised if it were a fair bit less than that.
