of our printing, because for printing a dozen copies of anything the lever press is the cheaper. There will be shoemakers who not only mend shoes but occasionally make them for customers who want other than standard kinds; and local tailors are sure to survive. Only in the general market and in the making of standard goods is size essential to success. _A Considerable Number of Competitors Assumed._--The most striking phenomenon of our time is the consolidation of independent establishments by the forming of what are usually called trusts; and this and all the approaches to it are precluded by the static hypothesis. There is a question whether, after competition has reduced the establishments in one subgroup to a half dozen or less, they would not, even without forming a trust, act as a quasi-monopoly. This question we have at the proper point fully to discuss, but here it is necessary to assume that nothing which creates even a quasi-monopoly exists. We shall find that competition usually would, in fact, survive and be extremely effective among as few as five or six competitors, till they formed some sort of union with each other. To avoid all uncertainty we assume that in the static state in which values, wages, and interest are natural and in which each subgroup has its perfectly normal share of labor and capital, there are competitors enough in each occupation to preclude all question as to the continuance of an active rivalry. _Static Values and Prices._--The equilibrium referred to requires that all values should stand at their static levels, which means that the prices of goods should be the "cost prices" of the older economists. The _entrepreneur_ should make no net profit on the goods he is producing. The wages of labor must be productivity wages, since each man must get the amount of wealth that he brings into existence. Interest on capital needs, in like manner, to be productivity interest, and each unit of capital must get the amount it creates. Moreover, the prices of goods, as expressed in money, must be accurate representations of the comparative values of goods. All these features mark the static state; but the most obvious mark of distinction is the absence of movement from group to group. We shall see that values are ultimately measured in marginal labor, and as the value of money is measured in the same way, it follows that the price of each article, as expressed in money, is in a static state a correct expression of the comparative amount of labor that will make it. And the entire relation of commodities to each other and to labor can be expressed by the medium of currency. If a unit of labor produces gold enough to make an eagle, and if any commodity sells for ten dollars, it will be safe to infer that it is also produced by one unit of labor. If one commodity sells for ten dollars and another for five dollars, the former is the product of twice as many units of marginal labor as is the latter.
