The difficulty from which this confusion has sprung is in the preaccepted theory of wages. For reasons which I have before assigned, it has seemed to them a self-evident truth that the wages of certain classes of laborers depended upon the ratio between capital and the number of laborers. But there are certain kinds of reward for exertion to which this theory evidently will not apply, so the term wages has in use been contracted to include only wages in the narrow common sense. This being the case, if the term interest were used, as consistently with their definitions it should have been used, to represent the third part of the division of the produce, all rewards of personal exertion, save those of what are commonly called wage-workers, would clearly have been left out. But by treating the division of wealth as between rent, wages, and profits, instead of between rent, wages, and interest, this difficulty is glossed over, all wages which will not fall under the preaccepted law of wages being vaguely grouped under profits, as wages of superintendence. To read carefully what economists say about the distribution of wealth is to see that, though they correctly define it, wages, as they use it in this connection, is what logicians would call an undistributed term—it does not mean all wages, but only some wages—viz., the wages of manual labor paid by an employer. So other wages are thrown over with the return to capital, and included under the term profits, and any clear distinction between the returns to capital and the returns to human exertion thus avoided. The fact is that the current political economy fails to give any clear and consistent account of the distribution of wealth. The law of rent _is_ clearly stated, but it stands unrelated. The rest is a confused and incoherent jumble. The very arrangement of these works shows this confusion and inconclusiveness of thought. In no politico-economic treatise that I know of are these laws of distribution brought together, so that the reader can take them in at a glance and recognize their relation to each other; but what is said about each one is enveloped in a mass of political and moral reflections and dissertations. And the reason is not far to seek. To bring together the three laws of distribution as they are now taught, is to show at a glance that they lack necessary relation.
