If I've read the article correctly, it sounds IF GM does declare bankruptcy they will have cost the taxpayers more money then they would have receiving bail out loans...
$1:
Chief Operating Officer Fritz Henderson said at the time that the government would be the only place the company could get financing for a Chapter 11 reorganization, because the credit markets are frozen. The worst-case bankruptcy scenario would cost the government $100-billion, Mr. Henderson said, because revenue would severely drop due to a lack of sales.
And what would happen to the retirees living off of pensions & requiring healthcare benefits from GM?
