I think this is probably true in isolation, but I'm not sure if that's the wisest course right now in the current situation. We're on the edge of a huge recession, unemployment is high, and the credit market is crippled. Somebody needs to take a step back and figure out how a big 3 bankruptcy works into a much bigger picture.
It would go a long way towards straightening the currently unsustainable trend of the big 3 automakers. Those who survive it (if any) will better exponentially better positioned to deliver a market-competitive product that both a) sells and b) is profitable.
But make no mistake -- it's going to be tough, and it's going to hurt a LOT of people and a LOT of families. However, that's going to happen regardless of whether or not the big 3 gets $25 billion. The American car companies of old are history. *If* they can survive it will be a drastically different landscape of employee/employer relationships, vendor relationships, Unions, workers salaries, etc.
