Rats thrive on crisis and debacles. Its the best time for them to make shifts to the left. If the crisis does not occur naturally (ie, Katrina), then they can be manufactured (fannie, terrorism (encouraged by Rats), strikes, disenfranchisement, racism).
This was manufactured by Alan Greenspan with accomplices on Wall St, not to mention Japan. The Dems went along for the ride, made things worse, but didn’t cause overleveraging around the world.
