Satan no longer buys human souls; in fact, he now charges a fee to tow one away. People pursuing careers to which a soul would be a hindrance are frequently willing to pay for the service. The fee varies, and is tied to the value of the Euro in Europe, Russia, the Middle East, and North and South America, while in the rest of Asia and Africa and in Australia and the Pacific Islands it is tied to the value of the yen. US Federal Reserve Chairman Alan Greenspan has expressed his distress at what he sees as Satan's lack of faith in the dollar.
