The best parallel one can use to describe the Iranian power structure is the Mafia. The "Genovese," "Gambino," "Bonano," "Colombo" and "Lucchese" type families have their equivalent in the ayatollahs Rafsanjani, Jannati, and Khamenei, Messbaheh-Yazdi, Vaa’ezeh-Tabasi and man, many more, each one with a private militia at their disposal. Just like the Mafia families divvied territory and areas of influence, the Ayatollahs divvy interests and "monopolize" particular businesses. For example, Rafsanjani started his personal fortune by supervising all oil deals, while Tabassi "looks after" the major charity organization, the Shrine of Imam Reza, which is a huge source of liquid cash. Rafsanjani later diversified his business, and was the mullah who most profited when ex-President Clinton allowed the import of pistachios and carpets from Iran. (FrontPageMag.com, 01/27/05.)
I have heard from a source that one mullah owns a big Asian electronics company. If you have any information on this, please send me an email or comment on this post.
