The straws in the wind are hard to ignore: If you visit any car dealership in America today you will see row after row of unsold S.U.V.’s. And if you own a gas guzzler already, good luck. On Thursday, The Palm Beach Post ran an article on your S.U.V. options: “Continue to spend upward of $100 for a fill-up. Sell or trade in the vehicle for a fraction of the original cost. Or hold out and park the truck in the driveway for occasional use in hopes the market will turn around.” Just be glad you don’t own a bus. Montgomery County, Md., where I live, just announced that more children were going to have to walk to school next year to save money on bus fuel.On top of it all, our bank crisis is not over. Two weeks ago, Goldman Sachs analysts said that U.S. banks may need another $65 billion to cover more write-downs of bad mortgage-related instruments and potential new losses if consumer loans start to buckle.
