Fallacy of Destruction as an Economic Advantage

A young hoodlum heaves a brick through the window of a baker’s shop. The shopkeeper runs out furious, but the boy is gone. A crowd gathers, and begins to stare with quiet satisfaction at the gaping hole in the window and the shattered glass over the bread and pies.

After a while the crowd feels the need for philosophic reflection. And several of its members are almost certain to remind each other or the baker that, after all, the misfortune has its bright side. It will make business for some glazier (window maker).

As they begin to think of this they elaborate upon it. How much does a new plate glass window cost? Two hundred and fifty dollars? That will be quite a sum. After all, if windows were never broken, what would happen to the glass business? Then, of course, the thing is endless. The glazier will have $250 more to spend with other merchants, and these in turn will have $250 more to spend with still other merchants, and so ad infinitum. The smashed window will go on providing money and employment in ever-widening circles.

The logical conclusion from all this would be, if the crowd drew it, that the little hoodlum who threw the brick, far from being a public menace, was a public benefactor.

Now let us take another look. The crowd is at least right in its first conclusion. This little act of vandalism will in the first instance mean more business for some glazier. But the shopkeeper will be out $250 that he was planning to spend for a new suit. Because he has to replace a window, he will have to go without the suit (or some equivalent luxury or need). Instead of having a window and $250 he now has merely a window. Or, as he was planning to buy the suit that very afternoon, instead of having both a window and a suit he must be content with the window and no suit.

If we think of the baker as part of a community, the community has lost a new suit that might otherwise have come into being, and is just that much poorer.

The glazier’s gain in business, in short, is merely the tailor’s loss of business. No new “employment” has been added. The people in the crowd were thinking only of two parties to the transaction, the baker and the glazier. They had forgotten about the potential third party involved, the tailor. They forgot him precisely because he will not now enter the scene. They will see the new window in the next day or two. They will never see the extra suit, precisely because it will never be made. They see only what is immediately visible to the eye.

Thus we see the fallacy of destruction as an economic advantage. Anybody, one would think, would be able to avoid this fallacy after a few moment’s thought. Yet this fallacy, under a hundred different disguises, is the most persistent in the history of economics. It is solemly reaffirmed every day by great captains of industry, by chambers of commerce, by labor union leaders, by editorial writers and newspaper columnists and radio and television commentators, by learned statisticians using the most refined techniques, by professors of economics in our best universities.
