It is exactly the same with money if the term be rightly understood. Understood aright, money, being the measure and representative of wealth, is in the main, the measure and the representative of dead men’s toil; for, rightly understood, wealth is almost entirely the product of the labor of by-gone generations. This product, we have seen, involves the element of time as the chief factor. And so we discover how money, properly understood, is connected with time—the main function of money is to measure and represent the accumulated products of the labor of past generations. Hoarded money is like an iron “inch” upon a shelf—a useless lump; but when used as a measure and representative of wealth rightly understood, money renders invaluable service, for it then serves to measure and represent the living fruit of dead men’s toil. For this reason, it is useless to argue who is the more important, the capitalist who has legal possession of most of the material fruit of dead men’s toil, or the laborer who has legal possession of but little of it. In the laborer, we do not now really look for his physical muscular labor ALONE; for this is replaced by mechanical or animal power as soon as it can be. What we do need from labor, and what we will always need, is his BRAIN—HIS TIME-BINDING POWER. The population of the world may be divided into different classes; if the classes are not here enumerated in the customary way, it is because it is necessary to classify human beings, as nearly as possible according to their “power-value.” There is no assertion that this is an ideal classification, but if someone is moved to exclaim—“what a foolish, unscientific division!”—I will answer by saying: “I grant that the division is foolish and unscientific; but IT IS THE ONLY DIVISION WHICH CORRESPONDS TO FACTS IN LIFE, and it is not the writer’s fault. By this ‘foolishness’ some good may be accomplished.” From an engineer’s point of view humanity is apparently to be divided into three classes; (1) the intellectuals; (2) the rich; and (3) the poor. This division would seem to be contrary to all the rules of logic, but it corresponds to facts. Of course some individuals belong to two of the classes or even to all three of them, an after-war product, but essentially, they belong to the one class in proportion to the characteristic which is the most marked in their life; that is, in the sense of social classes—BASED ON MAGNITUDE OF VALUES. (1) The intellectuals are the men and women who possess the knowledge produced by the labor of by-gone generations but do not possess the material wealth thus produced. In mastering and using this inheritance of knowledge, they are exercising their time-binding energies and making the labor of the dead live in the present and for the future.
