I was wondering if there have been studies done to show the turn over for a family or Cosa Nostra in general in a year or period. I wanted to see if we could compare recent years with the highs of the 60s and 70s for a comparison.

For example the Genovese family were estimated to make X amount in 2010, in 1970 they made this. I realise this is very hard to put a price on organised crime but I think there have been estimates made. Just thinking of the big families in the 70s the turnover must of been ridiculous, however even today it would surely rival big legitimate businesses.
