I think that at least the modern mobsters prefer another way to made money from drugs like impose a tribute to the drug dealers.
Because today there few mobsters that would risk 20 y and more for selling coke or heroin while can made easly money with gambling,loansharking etc.
The case of Matty Madonna that get 30 y for selling H and dosent speak doesnt exist today,more mobsters prefer his blood family that the other family.
