By Paul Krugman in the NYTimes.com (12/3/07):
...nobody knows where the [subprime mortgage] financial toxic waste is buried. Citigroup wasn’t supposed to have tens of billions of dollars in subprime exposure; it did. Florida’s Local Government Investment Pool, which acts as a bank for the state’s school districts, was supposed to be risk-free; it wasn’t (and now schools don’t have the money to pay teachers).
How did things get so opaque? The answer is “financial innovation” — two words that should, from now on, strike fear into investors’ hearts.
O.K., to be fair, some kinds of financial innovation are good. I don’t want to go back to the days when checking accounts didn’t pay interest and you couldn’t withdraw cash on weekends.
But the innovations of recent years — the alphabet soup of C.D.O.’s and S.I.V.’s, R.M.B.S. and A.B.C.P. — were sold on false pretenses. They were promoted as ways to spread risk, making investment safer. What they did instead — aside from making their creators a lot of money, which they didn’t have to repay when it all went bust — was to spread confusion, luring investors into taking on more risk than they realized.
Why was this allowed to happen? At a deep level, I believe that the problem was ideological: policy makers, committed to the view that the market is always right, simply ignored the warning signs. We know, in particular, that Alan Greenspan brushed aside warnings from Edward Gramlich, who was a member of the Federal Reserve Board, about a potential subprime [mortgage] crisis.
Also, from a similar column by Paul Krugman (on 12/21/07):
"Given the role of conservative ideology in the mortgage disaster, it’s puzzling that Democrats haven’t been more aggressive about making the disaster an issue for the 2008 election. They should be: It’s hard to imagine a more graphic demonstration of what’s wrong with their opponents’ economic beliefs."
