Chapter I. Of The Requisites Of Production.

to our illustration of the alphabet, it is evident that a certain amount of capital united with labor (constituting what may be called a productive engine) lies behind the production of A (such as the plow, for example), and to which its existence is due. The same is true of Z. Suppose that 5,000 of Z is produced, of which 4,000 is enough to reimburse the capital used up by labor in the operation, and that the owner of commodity Z spends the remaining 1,000 Z in exchange for 1,000 of commodity A. It is evident (no money being used as yet) that this exchange of goods is regulated entirely by the desires of the two parties to the transaction. No more goods are created simply by the exchange; the simple process of exchange does not keep the laborers engaged on A occupied. And yet the owner of Z had a demand for commodity A; his demand was worthless, except through the fact of his production, which gave him actual wealth, or purchasing power, in the form of Z. His demand for commodity A was not the thing which employed the laborers engaged in producing A, although the demand (if known beforehand) would cause them to produce A rather than some other article—that is, the demand of one quantity of wealth for a certain thing determines the direction taken by the owner of capital A. But, since the exchange is merely the form in which the demand manifests itself, it is clear that the demand does not add to production, and so of itself does not employ labor. Of course, if there were no desires, there would be no demand, and so no production and employment of labor. But we may conclude by formulating the proposition, that wealth (Z) offered for commodities
