A good and brief description of how the housing boom, deregulation, CDOs, and market ideology led us into this mess…

Because these loans go to people stretching to afford a house, they come with higher interest rates — even if they’re disguised by low initial rates — and thus higher returns. The mortgages were then sliced into pieces and bundled into investments, often known as collateralized debt obligations, or C.D.O.’s (a term that appeared in this newspaper only three times before 2005, but almost every week since last summer). Once bundled, different types of mortgages could be sold to different groups of investors.
Investors then goosed their returns through leverage, the oldest strategy around. They made $100 million bets with only $1 million of their own money and $99 million in debt. If the value of the investment rose to just $101 million, the investors would double their money. Home buyers did the same thing, by putting little money down on new houses, notes Mark Zandi of Moody’s Economy.com. The Fed under Alan Greenspan helped make it all possible, sharply reducing interest rates, to prevent a double-dip recession after the technology bust of 2000, and then keeping them low for several years.
All these investments, of course, were highly risky. Higher returns almost always come with greater risk. But people — by “people,” I’m referring here to Mr. Greenspan, Mr. Bernanke, the top executives of almost every Wall Street firm and a majority of American homeowners — decided that the usual rules didn’t apply because home prices nationwide had never fallen before. Based on that idea, prices rose ever higher — so high, says Robert Barbera of ITG, an investment firm, that they were destined to fall. It was a self-defeating prophecy.
