OKAY--I KNOW LITTLE ABOUT ECONOMICS: But is there any concept of a corporation's lifespan? I 'm listening to NPR and they're talking about United Airlines and their bankruptcy and them trying to shift their pension plans to the government because the plans are these big dead weights that are preventing United from seeking investors. And I'm thinking, why don't they just let United die? Sell everything off, use that to fund the pensions, let somebody else step into or grow in the marketplace. I can't imagine what is gained by keeping it alive. I mean, I think I know the answer: it's too big to let it die. But that's not a good reason.
