The way I see it, a bankruptcy of these companies wouldn't mean the companies shutting down and everyone getting fired - so while there are 2.5 million or so jobs on the line, connected to these companies, I don't believe that all, or indeed, even most of them would go.
The problem is that the companies, all of them to some extent, but some are worse than others, are inefficient and have suffered badly under poor management. What is needed, is dramatic improvements in inefficiency, and a better focus on making a product that people are prepared to buy.
In short, this means that jobs will have to go. The mindless pursuit of market share that GM and Ford made, is pointless given the growth in competition from elsewhere, and that has been much of the foundations of the current situiation. SInce the problem is that the companies are set up to build more than there is a market for, whether there is a bailout or not, jobs will have to go. If they get bailed out, but the companies don't downsize and make efficienc savings, then nothing will have changed.
The choice really is then between: Letting the problem continue, and have the state prop up non-jobs, or fixing the problem, either with a bail-out and forced reorganisation, or reorganisation under existing Chapter 11 banmkruptcy. The first is clearly not a solution. The capitalist in me finds favor in the bankruptcy route, the only problem is what ripples it may cause. The bankruptcy of Lehman took the financial crisis up a gear, and probably took the stockmarket down a couple of thousand points, and the shock wave is still echoing through the credit markets. The fear that could result from a BK the size of GM may well cause severe damage, which is why I'm beginning to lean towards a bailout and reorganisation in a more controlled fashion. Not because it will make any difference to jobs and productivity, but because of the overall feeling of confidence in the economy and in business.
