Matt Taibbi, the best political writer on the planet (and the sane man’s Hunter S. Thompson) puts the smackdown on some National Review douchebag in a conversation with New York Magazine. Not to be missed.

Byron York: I think that Fannie Mae and Freddie Mac were also major factors. And I believe that many of the problems in the mortgage area can be attributed to the confluence of Democratic and Republican priorities: the Democrats’ desire to give mortgages to people, particularly minorities, who could not afford them, and the Republicans’ desire to achieve an “ownership society,” in part by giving mortgages to people who could not afford them. Again, I believe that if you are suggesting that the financial crisis is a Republican creation, or even more specifically a McCain creation, I think you’re on pretty shaky ground.

Matt Taibbi: Oh, come on. Tell me you’re not ashamed to put this gigantic international financial Krakatoa at the feet of a bunch of poor black people who missed their mortgage payments. The CDS market, this market for credit default swaps that was created in 2000 by Phil Gramm’s Commodities Future Modernization Act, this is now a $62 trillion market, up from $900 billion in 2000. That’s like five times the size of the holdings in the NYSE. And it’s all speculation by Wall Street traders. It’s a classic bubble/Ponzi scheme. The effort of people like you to pin this whole thing on minorities, when in fact this whole thing has been caused by greedy traders dealing in unregulated markets, is despicable.

B.Y.: I was struck by the recent Senate testimony of James Lockhart, who is head of the Federal Housing Finance Agency, about the sheer recklessness of Fannie in recent years. Despite “repeated warnings about credit risk,” Lockhart testified, Fannie became more reckless in 2006 and 2007 than they had been in the scandal-ridden tenure of Franklin Raines (who departed in 2004). In 2005, Lockhart said, 14 percent of Fannie’s new business was in risky loans. In the first half of 2007, it was 33 percent. So something terribly wrong was going on there, and it became a significant part of the present problem.

M.T.: What a surprise that you mention Franklin Raines. Do you even know how a CDS works? Can you explain your conception of how these derivatives work? Because I get the feeling you don’t understand. Or do you actually think that it was a few tiny homeowner defaults that sank gigantic companies like AIG and Lehman and Bear Stearns? Explain to me how these default swaps work, I’m interested to hear.

Because what we’re talking about here is the difference between one homeowner defaulting and forty, four hundred, four thousand traders betting back and forth on the viability of his loan. Which do you think has a bigger effect on the economy?
