Let us suppose I told you of a certain doctrine in which millions of people believe without ever having read the book in which it is contained, which is predicated upon a situation that has never existed, and promises positive consequences that not only have never been delivered, but we are told cannot even be measured and cannot be realized without achieving something that has never been done before in the history of man. Furthermore, the doctrine was developed by a successful gambler and politician with absolutely no credentials or qualifications on the subject, which he had never even encountered before the age of 27, in tandem with a related theory that is so obviously insane that barely anyone has ever even heard of it.
So long as we are careful to set aside any reliance upon the genetic fallacy, does this sound like a doctrine that is not only infallible, but one that it would be crazy to even consider questioning? And yet, the fervor with which the advocates of the free-trade doctrine defend David Ricardo’s outdated, disproven theory of comparative advantage and decry those who question it is so ferocious as to indicate the nature of a belief that can only be described as religious.
