This Seems Bad

Not that I understand economics, but I don't like the sound of this:

The long-feared capitulation of American consumers has arrived. According to Thursday’s G.D.P. report, real consumer spending fell at an annual rate of 3.1 percent in the third quarter; real spending on durable goods (stuff like cars and TVs) fell at an annual rate of 14 percent.

To appreciate the significance of these numbers, you need to know that American consumers almost never cut spending. Consumer demand kept rising right through the 2001 recession; the last time it fell even for a single quarter was in 1991, and there hasn’t been a decline this steep since 1980, when the economy was suffering from a severe recession combined with double-digit inflation.

Krugman goes on to explain why this shouldn't sound very good, and isn't.
