Isn't this how the Mafia obtained great power in the United States - by providing illegal services at huge markups?
I believe that there is a large and vastly unreported element of criminals. Keep in mind that any good criminal, like a good businessman, grows and diversifies. I think we will wake up one day with a large organized crime problem which got its start with the false document business.
I think we're already there. I can't prove anything, of course, I am not an intelligence agency unto myself, but I'll just bet that a lot of the fake ID's the 9/11 terrorists had were obtained from the Mexican counterfeiters already in place.
