Alan Greenspan knew exactly what he was doing when he allowed the credit market to loosen up and the housing market to bubble--i.e., become significantly overpriced, and helped his friends profit from both the bubble and the collapse. Yep, he and Ayn Rand, friends forevah. Slightly longer version, Alan Greenspan knowingly created an unsupportable bubble that was bound to collapse. By doing so, he and his very good buddies became very very very rich. This is, the only word for it, evil. He used his position as the Federal Reserve Chairman to line his own pockets and impoverish the rest of us.
A democracy cannot exist as a permanent form of government. It can only exist until a majority of voters discover that they can vote themselves largess out of the public treasury.
