The Economist's economics blog didn't appreciate David Brooks' most recent column suggesting that communitarianism will ultimately prove superior to individualism.
"He argues people can never be truly rational, and happiness
really comes from relationships and being part of a community. This
seems inconsistent with most economic theory, which assumes that
individuals behave rationally and act in their best interest.
Ultimately, such behaviour results in a better outcome for all."
Simply noting that Brooks has too much sense to take the simplifying assumptions of economics as gospel is certainly no refutation of his argument. People are not, and will not be homo-economicus. Methodological individualism is an analytical tool for showing us how one would act if these things were true. While we will replicate this behavior more often than we would like to admit, I would hesitate to use this as an axiom by which I divined the secret to human behavior.
It's often said that a poor argument for your position is often more harmful to it than a stronger argument against it. This is certainly true in this instance.
What he ought to have said, is simply what Hayek said in Law, Legislation and Liberty. As I don't have it in front of me at the moment, I'm forced to paraphrase. In essence, it was Hayek's contention, not that people were perfectly rational, but that if institutions were drawn up to encourage freedom and responsibility that people would be forced to be more rational if they were to sustain their livelihood.
Unsurprisingly, firms, designed for the purpose of profit maximization, more often approximate this reality than individuals, whose purposes are as numerous as the individuals themselves.
