As the laborer who works for an employer does not get his wages until he has performed the work, his case is similar to that of the depositor in a bank who cannot draw money out until he has put money in. And as by drawing out what he has previously put in, the bank depositor does not lessen the capital of the bank, neither can laborers by receiving wages lessen even temporarily either the capital of the employer or the aggregate capital of the community. Their wages no more come from capital than the checks of depositors are drawn against bank capital. It is true that laborers in receiving wages do not generally receive back wealth in the same form in which they have rendered it, any more than bank depositors receive back the identical coins or bank notes they have deposited, but they receive it in equivalent form, and as we are justified in saying that the depositor receives from the bank the money he paid in, so are we justified in saying that the laborer receives in wages the wealth he has rendered in labor. That this universal truth is so often obscured, is largely due to that fruitful source of economic obscurities, the confounding of wealth with money; and it is remarkable to see so many of those who, since Dr. Adam Smith made the egg stand on its head, have copiously demonstrated the fallacies of the mercantile system, fall into delusions of the very same kind in treating of the relations of capital and labor. Money being the general medium of exchanges, the common flux through which all transmutations of wealth from one form to another take place, whatever difficulties may exist to an exchange will generally show themselves on the side of reduction to money, and thus it is sometimes easier to exchange money for any other form of wealth than it is to exchange wealth in a particular form into money, for the reason that there are more holders of wealth who desire to make some exchange than there are who desire to make any particular exchange. And so a producing employer who has paid out his money in wages may sometimes find it difficult to turn quickly back into money the increased value for which his money has really been exchanged, and is spoken of as having exhausted or advanced his capital in the payment of wages. Yet, unless the new value created by the labor is less than the wages paid, which can be only an exceptional case, the capital which he had before in money he now has in goods—it has been changed in form, but not lessened. There is one branch of production in regard to which the confusions of thought which arise from the habit of estimating capital in money are least likely to occur, inasmuch as its product is the general material and standard of money. And it so happens that this business furnishes us, almost side by side, with illustrations of production passing from the simplest to most complex forms.
