Perhaps you are one of the smart ones. But an awful lot of "City types" thought the same, until the economy took a dive, and then their vast geared-up paper fortunes were worth zilch. One would think somebody worth $100M would have stashed away $10M for a rainy day, but these people thought that that would be a waste, reducing their working capital by 10%... so all they ended up with was some Ferrari (bought on finance too), and a house with a 100% mortgage
