The consumers by their buying and abstention from buying elect the entrepreneurs in a daily repeated plebiscite as it were. They determine who should own and who not, and how much each owner should own.

As is the case with all acts of choosing a person — choosing holders of public office, employees, friends, or a consort — the decision of the consumers is made on the ground of experience and thus necessarily always refers to the past. There is no experience of the future. The ballot of the market elevates those who in the immediate past have best served the consumers. However, the choice is not unalterable and can daily be corrected. The elected who disappoints the electorate is speedily reduced to the ranks.

Each ballot of the consumers adds only a little to the elected man’s sphere of action. To reach the upper levels of entrepreneurship he needs a great number of votes, repeated again and again over a long period of time, a protracted series of successful strokes. He must stand every day a new trial, must submit anew to reelection as it were.

It is the same with his heirs. They can retain their eminent position only by receiving, again and again, confirmation on the part of the public. Their office is revocable. If they retain it, it is not on account of the deserts of their predecessor, but on account of their own ability to employ the capital for the best possible satisfaction of the consumers.

The entrepreneurs are neither perfect nor good in any metaphysical sense. They owe their position exclusively to the fact that they are better fit for the performance of the functions incumbent upon them than other people are. They earn profit not because they are clever in performing their tasks, but because they are more clever or less clumsy than other people are. They are not infallible and often blunder. But they are less liable to error and blunder less than other people do. Nobody has the right to take offense at the errors made by the entrepreneurs in the conduct of affairs and to stress the point that people would have been better supplied if the entrepreneurs had been more skillful and prescient. If the grumbler knew better, why did he not himself fill the gap and seize the opportunity to earn profits? It is easy indeed to display foresight after the event. In retrospect all fools become wise.

A popular chain of reasoning runs this way: The entrepreneur earns profit not only on account of the fact that other people were less successful than he in anticipating correctly the future state of the market. He himself contributed to the emergence of profit by not producing more of the article concerned; but for intentional restriction of output on his part, the supply of this article would have been so ample that the price would have dropped to a point at which no surplus of proceeds over costs of production expended would have emerged. This reasoning is at the bottom of the spurious doctrines of imperfect and monopolistic competition. It was resorted to a short time ago by the American Administration when it blamed the enterprises of the steel industry for the fact that the steel production capacity of the United States was not greater than it really was.
