Collateralized Debt Obligations

koganbot"Repackaging dubious loans into collateralized debt obligations creates a lot of perfectly safe, AAA assets that will never go bad."
The sentence is from Paul Krugman's column in today's NY Times. He's using it as an example of sophistry (which his dictionary defines as "a deliberately invalid argument displaying ingenuity in reasoning in the hope of deceiving someone"), though I'd think that putting the word "dubious" into the sentence makes it not sophistic. (The first half of Krugman's sentence describes what investment funds actually did, not what they said they were doing, right? So no one ever actually made the argument. Or did someone?)
But anyway, if I understood that sentence I'd understand how we got into the current financial situation (recession believed to be looming, is possibly here already), but I don't know enough about either economics or Wall Street to understand that sentence.
I know what "collateral" means (a car, house, etc. that backs up a debt, so that if the debtor can't pay, the lender gets to take possession of the car, house, etc.). And I know that AAA means that the asset is rated highly (considered "reliable and stable" by a credit rating company such as Standard & Poor's). But I don't know how you get from "dubious loans" - i.e., mortgages at onerous terms given to unwary home buyers whom one could not reasonably assume would be able to pay off the mortgages or understand what they were getting into - to "collateralized debt obligations" and then to "AAA assets." Which is to say I don't know what happened, or what the assets were. I gather that the cautious responsible investors who purchased (?) the "AAA assets" were, in effect, investing in the risky subprime mortgages without being told that this was what they were investing in. (Is that right?) So it's not just the homeowners who took out the subprime mortgages who are struggling for cash and therefore not spending, but also a bunch of solid citizen investors, hence a lot of people and firms are scrapping for money rather than spending or investing it. (Right?) This tends to depress an economy.
So, anyway, what happened?
(By the way, Krugman's really good, even if he doesn't always have the space to explain everything. I read his blog whenever I get the chance.)
