Generally, I agree with Friedman. However, what we as a society seem to be missing is that it is in our own long-term self interests not to be so greedy, not to push the system as far as it will allow, not to take advantage of every opportunity when it is disadvantageous to someone else, because the collective failure of the system is bad for our self-interests. The mortgage crisis is a perfect example of that: too many people acting greedily, without regard to harm to others, and eventually the system collapses from being pulled in too many opposing directions. Then we all suffer. And then, suddenly, we collectively whine and moan and demand for someone (i.e., the government) to do something about it. And the government responds. Like a parent to a naughty child.
Lots of folks get upset at the phrase "spreading the wealth." Folks don't want government sticking its nose in our finances and playing some modern-day version of Robin Hood. But we're screaming for that help now, as shut-downs, layoffs, loan-freezes, and other market-stopping events happen as a result of our collective poor decisions. We would have no need for oversight, for bailouts, for multi-billion-dollar stimulus packages were it not for our own irresponsibility. --If mortgage companies had thought about the long-term harm of bad loans with variable interest rates rather than the short-term benefit from selling those loans; if home buyers had stayed within their means; if appraisers had not continued re-upping the "value" of real estate; if any one type of player in that system had thought about what was good for everyone involved in those transactions. If we had been more responsible, we wouldn't be here, begging for help.
So, we can blame our representatives, our presidents, our governmental bodies for spending all of this money for the various rescue attempts; but they are only doing that which we've requested. We're the guy who went parasailing in a hurricane. Should we leave him stuck in the tree because of his stupidity? Or do we organize a rescue effort?
I don't really know the right answer to the question. My instinct is to let us get ourselves out of that tree, to learn something from the painful stupidity. But I'm not an economist, and I don't know if we can get ourselves out. Irrespective of the right way to get out of this mess, though, I think we should be sure to (to paraphrase the evil catch-phrase from the election) "spread the blame:" we wouldn't be talking about nationalized banking systems and bailouts if we had managed ourselves better.
