In the chapter on the theory of competition we saw that, if we conceived the results of the labor of the whole community to be placed in a common storehouse and gave to each man the right to draw from it an amount just equal to the benefit derived from the goods which he had placed within it, the ideal of a perfect system of distribution of wealth would be realized. No human judgment, however, is, or ever can be, competent to measure the exact industrial benefits which each person confers upon the community at large. We must inevitably permit men to measure the result of their own work by securing for it such an amount of the results of others' work as they can induce them to give in exchange. But while we cannot measure exactly the benefit which each person confers, we can see cases in which the reward received is manifestly out of all proportion to the benefit conferred. Consider the fortunes which have been accumulated by some of our Midases of the present decade. It is quite certain that the benefits which Cornelius Vanderbilt, for instance, conferred on the community by his enterprise and business sagacity, by his work in opening new fields of industry, forming new channels for commerce, etc., were so valuable that he honestly earned the right to enjoy a large fortune. It is equally certain that a great part of his gains had nothing whatever to do with any benefit conferred upon the community, and that the fortune of $100,000,000 or so which he accumulated was an example of inequitable distribution of the products of the world's industry. Stating this in the form of a general principle, we should say: The amount of wealth which any man receives should bear some approximate relation to the benefit which he confers upon the world.
We have already stated that, by the law of supply and demand, the rewards of each worker are regulated in theory even more perfectly in accordance with our ideas of liberty than they could be on the basis of actual benefit conferred. For it is inconceivable that people would submit to pay for what was beneficial to them instead of what they desired. A man who prefers to purchase wines instead of books with his surplus money would think it a great injustice if he were prevented from doing as
