The Parable of the Broken Window* by Frédéric Bastiat.
First published in 1850.
~Have you ever been witness to the fury of that solid citizen, John Public, when his incorrigible son has happened to break a pane of glass? If you have been present at this spectacle, certainly you must also have observed that the onlookers, even if there are as many as thirty of them, seem with one accord to offer the unfortunate owner the selfsame consolation: "It's an ill wind that blows nobody some good. Such accidents keep industry going. Everybody has to make a living. What would become of the glaziers if no one ever broke a window?"
1.6
Now, this formula of condolence contains a whole theory that it is a good idea for us to expose, flagrante delicto, in this very simple case, since it is exactly the same as that which, unfortunately, underlies most of our economic institutions.
1.7
Suppose that it will cost six francs to repair the damage. If you mean that the accident gives six francs' worth of encouragement to the aforesaid industry, I agree. I do not contest it in any way; your reasoning is correct. The glazier will come, do his job, receive six francs, congratulate himself, and bless in his heart the careless child. That is what is seen.
1.8
But if, by way of deduction, you conclude, as happens only too often, that it is good to break windows, that it helps to circulate money, that it results in encouraging industry in general, I am obliged to cry out: That will never do! Your theory stops at what is seen. It does not take account of what is not seen.
1.9
It is not seen that, since our citizen has spent six francs for one thing, he will not be able to spend them for another. It is not seen that if he had not had a windowpane to replace, he would have replaced, for example, his worn-out shoes or added another book to his library. In brief, he would have put his six francs to some use or other for which he will not now have them.
1.10
Let us next consider industry in general. The window having been broken, the glass industry gets six francs' worth of encouragement; that is what is seen.
1.11
If the window had not been broken, the shoe industry (or some other) would have received six francs' worth of encouragement; that is what is not seen.
1.12
And if we were to take into consideration what is not seen, because it is a negative factor, as well as what is seen, because it is a positive factor, we should understand that there is no benefit to industry in general or to national employment as a whole, whether windows are broken or not broken.
1.13
Now let us consider John Public.
1.14
On the first hypothesis, that of the broken window, he spends six francs and has, neither more nor less than before, the enjoyment of one window.
1.15
On the second, that in which the accident did not happen, he would have spent six francs for new shoes and would have had the enjoyment of a pair of shoes as well as of a window.
1.16
Now, if John Public is part of society, we must conclude that society, considering its labors and its enjoyments, has lost the value of the broken window.
1.17
From which, by generalizing, we arrive at this unexpected conclusion: "Society loses the value of objects unnecessarily destroyed," and at this aphorism, which will make the hair of the protectionists stand on end: "To break, to destroy, to dissipate is not to encourage national employment," or more briefly: "Destruction is not profitable."
1.18
What will the Moniteur industriel say to this, or the disciples of the estimable M. de Saint-Chamans, who has calculated with such precision what industry would gain from the burning of Paris, because of the houses that would have to be rebuilt?
1.19
I am sorry to upset his ingenious calculations, especially since their spirit has passed into our legislation. But I beg him to begin them again, entering what is not seen in the ledger beside what is seen.
1.20
*This is not to be confused with the text on sociology titled Fixing Broken Windows.
The fallacy of the onlookers' argument is that they considered the positive benefits of purchasing a new window, but they ignored the hidden costs to the shopkeeper and others. He was forced to spend his money on a new window, and therefore could not have spent it on something else. The child did not bring any net benefit to the town. Instead, he made the town poorer by the value of one window.
This lesson can be a foil to those idiots who promote littering (creates employment)
or those charletans citing the benefits of nature's fury (reconstruction), etc. Whether it is a small accident(a broken window) or a regional disaster(hurricane), society is all the poorer for the destruction and derives no net benefit.
