The God Father gets his cut from his "families" dealings because of protection from investigations and prosecutions because of the position he has. Each family controlled a different region but only answered to one "Godfather". Mafia on a global scale and instead of just drugs, gambling and booze, it is currency, governments and technology. Still hard to come to terms that we have been chumped by this. Death by a thousand cuts. When one has all the money they could ever need in a thousand lifetimes, I suppose a new game had to be found.
