BW's Mandel takes the Bureau of Economic Analysis numbers and finds that the American savings rate is somewere near 6.4% and Americans have cut spending by $200 billion or 3.1% over the past year. And over the past year Americans reduced spending on automobiles by 10.8% and clothing by 4.2%. But this still does not explain the steep decline of nearly 40% in the sales of automobiles for the Detroit carmakers and big declines for the Japanese carmakers also.
