Last night, on the Daily Show:
Alan Greenspan: "...well, you know, forecasting the economy is no better or worse than it was fifty years ago. It's based on human nature — panic and euphoria. If I had a better way to figure out which one people feel, I don't need any of the other data. The trouble is, we can't figure that out. The reason is that human nature isn't change. We can't improve ourselves."
Jon Stewart: "You just bummed the shit out of me."
Greenspan, of course, was the head of the US Federal Reserve from 1987 to 2006. This means he was one of the most powerful people in the world for almost two decades.
Congrats on the Emmy, Jon. You deserve it.
