The Mafia has a structure and chain of command like any other corporation. There are CEOs who run things, boards to answer to, midlevel managers climbing their way up, and even accountants. And while some people may joke that there's little difference between a corporate board and the Mafia, the fact is the Mafia's structure is one of the reasons the mob has been able to succeed in the business of crime. But like the business world, jealousy, people striving to get ahead, and office politics cause friction. But unlike the corporate world, in the mob when such upsets happen, people get killed.
