A little inside economics, a real serious issue I see the the relationship between GDP and government tax revenues. All the models have a fixed relationship between tax revenue and GDP. My guess is that many company's have very large tax loss provisions that they can move forward. So 2010 corporate tax receipts will not recover because company's will be witting off past losses. I have not reviewed the GM and Chrysler Bankruptcy documents, I really do not want to do so, but the judge may have allowed the two company's to carry forward their tax losses.
I see no chance of a growth in government tax revenue if GDP growth is less than 2.5%

It is a mistake to think businessmen are more immoral than politicians!
