One the one hand, our economists treat human beings as rational actors making choices to maximize their own economic benefit. On the other hand, the same companies that hire those economists also pay for advertising campaigns that use the raw materials of myth and magic to encourage people to act against their own best interests, whether it's a matter of buying overpriced fizzy sugar water or the much more serious matter of continuing to support the unthinking pursuit of business as usual in the teeth of approaching disaster.
