I think they are just doing it to help out the Japanese auto makers.
And for all the morons who think GM should just file bankrupcy, or just shut the doors, you had better hope it never ever happens. It would be a huge blow to the US economy, and would more than likely require a government bailout costing billions of dollars. The tentacles of GM's dollars in the US economy reach far and deep.
Just buy GM now, or pay for it in higher taxes later. GM will be around forever, and it will be even worse with the government halfway in charge of operations.
BTW, the first line is sarcasm in case your meter is broken.
