What exactly does the Mafia do?

The Mafia is a business that operates just like any other business - they want to make as much money as they can. In a way, they are more honest than most legal industries as they don't try to hide the fact that they are stealing your money and there isn't much you can do about it.

Most of them are involved in giving the public what it wants, but can't get legally - gambling, drugs and prostitution.
