If Mr. Greenspan had said two years ago what he's saying now, people might have borrowed less and bought more wisely. But he didn't, and now it's too late. There are signs that the housing market either has peaked already or soon will. And it will be up to Mr. Greenspan's successor to manage the bubble's aftermath.
How bad will that aftermath be? The U.S. economy is currently suffering from twin imbalances. On one side, domestic spending is swollen by the housing bubble, which has led both to a huge surge in construction and to high consumer spending, as people extract equity from their homes. On the other side, we have a huge trade deficit, which we cover by selling bonds to foreigners. As I like to say, these days Americans make a living by selling each other houses, paid for with money borrowed from China.

And here's where Mr. Greenspan is still saying foolish things. In his closing remarks he suggested that "an end to the housing boom could induce a significant rise in the personal saving rate, a decline in imports and a corresponding improvement in the current account deficit." Translation, I think: the end of the housing bubble will automatically cure the trade deficit, too.
Sorry, but no. A housing slowdown will lead to the loss of many jobs in construction and service industries but won't have much direct effect on the trade deficit. So those jobs won't be replaced by new jobs elsewhere until and unless something else, like a plunge in the value of the dollar, makes U.S. goods more competitive on world markets, leading to higher exports and lower imports.
So there's a rough ride ahead for the U.S. economy. And it's partly Mr. Greenspan's fault.
