The S&P 500 was down 41.9% in 1931 and 38.6% in 1937. In 1974 it was down 29.7%. What was it down by in 2008. In 2008 the S&P 500 was down 45.5%. This matched what happened in the Great Depression and we are not through 2008 yet as one can see from what is happening to the share price of Citigroup, other banks and the Detroit automakers. It a hell of a year and the errors during the Great Depression were different but there are errors in policy and in managing the crisis in this one also.

The NYT editorial took note of this on November 22, 2008, asking for funds however distasteful the behaviour of the automakers management may be. See this link. And public opinion could get the managemnt to resign or this could be a condition for signing onto the bridge loan from the government. In this particular issueof automakers Detroit automaker's management's serious errors will be written about years from now which combined with any indecision or slippage on the part of awmakers could lead to the economy and unemployment spiralling out of control, because so much is happening at the same time. It comes at atime when the storm is shifting to the consumer side to credit card and other consumer loans even as it is continuing to take its toll on the housing sector in the USA and on exports and the auto industry and other sectors around the world. ...
