Slate's pop-economist (every important media outlet is required to have a pop-economist who misuses the analytical tools of his inexact science to "prove" unlikely and surprising things each week) explains that housing foreclosures are good because after people are kicked out of their homes, other people get to move into those homes. Relevant excerpt: "I could use economics to explain why those readers are mistaken (a glut of homes on the market leads to falling prices, etc.), but that's unnecessarily complicated." [Slate]
