There is an insistent tendency among serious social scientists to think of any institution which features rhymed and singing commercials, intense and lachrymose voices urging highly improbable enjoyment, caricatures of the human esophagus in normal and impaired operation, and which hints implausibly at opportunities for antiseptic seduction as inherently trivial. This is a great mistake. The industrial system is profoundly dependent on commercial television and could not exist in its present form without it.

It is a well-established, though perhaps somewhat transparent, technique of argument, on encountering something which cannot easily be reconciled with preferred belief, to point to the exceptions. What does not invariably exist is then held not to exit.

If he suspects that economics, as it is conventionally taught, is, in part, a system of belief designed less to reveal truth than to reassure students and other communicants as to the benign tendency of established social arrangements, he will also be right.
