According to Shiite Muslim tradition, devout businessmen are expected to donate 20% of profits to their local mosques, which use the money to help the poor. By contrast, many bonyads seem like straightforward rackets, extorting money from entrepreneurs. Besides the biggest national outfits, almost every Iranian town has its own bonyad, affiliated with local mullahs. "Many small businessmen complain that as soon as you start to make some money, the leading mullah will come to you and ask for a contribution to his local charity," says an opposition economist, who declines to give his name. "If you refuse, you will be accused of not being a good Muslim. Some witnesses will turn up to testify that they heard you insult the Prophet Mohammad, and you will be thrown in jail." The Cosa Nostra meets fundamentalism.
