Probably best to make him feel that he doesn't know very much about it (which evidently, he doesn't). Ask him to explain evidence that goes contrary to his theory, or to apply his theory in cases where it obviously doesn't apply. Stuff like that. Don't hit him over the head with the fact that his entire knowledge of economics is wrong, that gets people on the defense.
