As a perplexed Alan Greenspan confessed to Congress about his own thinking in 2008 ... "I have found a flaw. I don't know how significant or permanent it is. But I have been very distressed by the fact." The congressman questioning him asked, "In other words, you found that your view of the world, your ideology, was not right. It was not working?" Greenspan replied, "Absolutely. Precisely. You know that's precisely the reason I was shocked. Because I have been going for forty years or more with very considerable evidence that it was working exceptionally well."
