Economics is haunted by more fallacies than any other study known to man. This is no accident. The inherent difficulties of the subject would be great enough in any case, but they are multiplied a thousandfold by a factor that is insignificant in, say, physics, mathematics or medicine - the special pleading of selfish interests.

ECONOMICS IS HAUNTED by more fallacies than any other study known to man. This is no accident. The inherent difficulties of the subject would be great enough in any case, but they are multiplied a thousandfold by a factor that is insignificant in, say, physics, mathematics or medicine — the special pleading of selfish interests.

there is a second main factor that spawns new economic fallacies every day. This is the persistent tendency of men to see only the immediate effects of a given policy, or its effects only on a special group, and to neglect to inquire what the long-run effects of that policy will be not only on that special group but on all groups. It is the fallacy of overlooking secondary consequences.

It follows that it is foolish and misleading to concentrate our attention merely on some special point.- to examine, for example, merely what happens to one industry without considering what happens in all. But it is precisely from the persistent and lazy habit of thinking only of some particular industry or process in isolation that the major fallacies of economics stem. These fallacies pervade not merely the arguments of the hired spokesmen of special interests, but the arguments even of some economists who pass as profound.

The spread-the-work schemes, in brief, rest on the same sort of illusion that we have been considering. The people who support such schemes think only of the employment they would provide for particular persons or groups; they do not stop to consider what their whole effect would be on everybody.<p>The spread-the-work schemes rest also, as we began by pointing out, on the false assumption that there is just a fixed amount of work to be done. There could be no greater fallacy. There is no limit to the amount of work to be done as long as any human need or wish that work could fill remains unsatisfied. In a modern exchange economy, the most work will be done when prices, costs, and wages are in the best relations to each other.

Contrary to a popular impression, profits are achieved not by raising prices, but by introducing economies and efficiencies that cut costs of production.
