I advocate nothing of the sort, just note that it is just as likely to work as the author's "plan", which (like most texts, really) is more of a testament to his personal psychological issues than to his reasoning abilities. Do we have a good reason to believe a society made of used-car salesmen would be worse than that made of Aspy scientists? :) If I advocate anything, it is that we base our social policies on careful study of actual society rather than a simplification made for people who are unable or unwilling to grasp the complexities of the human condition.
