How does one quantify the claim that a company is so large that its failure would take the national economy down with it? And here is a bit of a paradox. There is no such a thing as "too big to fail" in a free market. But from a practical point of view, we can't have the entire economy subject to the whims of any one corporate entity, so it must be that too big to fail means too big to exist. But any action to limit the size of companies also suggests that we no longer have a free market. Therefore, there can be no free market. It seems to me that puritan free-market policies are not in the public interest - it is a dead concept. While I still favor maintaining as free a market as possible, I now wonder why I was ever such a fan of the idea. Puritan free-market principles now seem about as logical to me as the notion of passing on penicillin in order to allow a bacterial infection to run its course, out of principle. That is to say that I see no evidence that a free market ultimately acts in the public interest any more than does a weather system, a bacterial infection, or any complex and self-serving, or chaotic system.
