As for what happens to the big 3 - I honestly think its questionable there will be 3 in a month; and that will follow another poor initial claims report and retail sales of black friday which I think will be very flat - low single digits over last year if anything at all, and possibly negative yr-yr.
If any of the big 3 fails, and that is a distinct possibility with the lame duck congress out of session, there will be significant consequences the likes of which it will be difficult to contemplate the outcome. I'm not advocating (any) bailouts - but from an investment point of view - be prepared to hunker down and be patient.
I do not think it would be a bad thing if the big 3 filed for bankruptcy. Remember, the CEOs went to congress looking for an unspecified amount-bailout that would allow them to continue to operate under the business as usual paradym. Only one of the CEOs when pressed said that they would have to file for bankruptcy if they didn't get the bailout. That was a clear sign that at least two are not hurting so as to need a bailout.
Now, lets talk about bankruptcy. If they do file for protection from their creditators, three things happen to the company; 1)They are bought out by another car company (this has happened before); 2) They must restructure and get rid of the drain on their finances (Delta and other airlines have been through this, put CEO saleries and jobs are at risk - less of a risk than #1 though); and 3) They go under like Trans World Airlines. The airline industry and the country didn't suffer that much from losing TWA and it allowed smaller leaner companies to find their place and grow.
Here is where bankruptcy will hurt - The small creditors will not get paid and there will be job losses and losses in some small businesses. Most will be protected though as they are subbusiness of the big three. Auto worker may have to restructure their contracts just like Delta pilots did to help the companies meet their goals and some factories will be closed (Ford has already closed their two plants in Atlanta), but this will lead the way to a leaner more efficient industry down the road. Yes, some one industry towns in Democratic districts will be devastated, but, most of those cities will quickly bounce back (One of the towns that was almost destroyed when they lost their auto plant is now the leader in internet wifi and telecommuting consulting - I need to find this town name).
So why is everyone afraid to allow these companies to go into bankruptcy protection? Why do we feel we must throw money at this problem? Citibank may have been to big to fail, but the BIG 3 (tiny 3 - IMO) are not too big to fail just as Delta and TWA(in it's time) was not too big to fail. Even if all 3 go away, there are still cars out there for sale. If we tried to protect USA made TV's like we are doing with the car industry, we would still have 26" color TVs that need TV repairmen to come out regularly (Does anyone still use a TV repairman? Do they even exist?) to fix the made in the USA poc. Just as the electronics industry moved on, the car industry must also to make way for new innovation and job creation.
All the doom and gloom about how the stock market and the US economy will be destroyed if we allow these auto companies to follow the normal course of a failing business and file for bankruptcy is so over played. Those CEOs are just unhappy that they were not Bear Stearns which benefited from being the first (anyone think BS would have been bailed out after AIG?) to ask for a bailout. The market will recover and I beleive the hit will be small in comparison to the financial companies meltdown. Lets pick our battles - the auto industry is a losing one for the US tax payer.
