decomposing profits into wages of superintendence, insurance, and interest, these economists, in assigning causes which fix the general rate of profit, speak of things which evidently affect only that part of profits which they have denominated interest; and then, in speaking of the rate of interest, either give the meaningless formula of supply and demand, or speak of causes which affect the compensation for risk; evidently using the word in its common sense, and not in the economic sense they have assigned to it, from which compensation for risk is eliminated. If the reader will take up John Stuart Mill's "Principles of Political Economy," and compare the chapter on Profits (Book II, Chap. 15) with the chapter on Interest (Book III, Chap. 23), he will see the confusion thus arising exemplified, in the case of the most logical of English economists, in a more striking manner than I would like to characterize.
Now, such men have not been led into such confusion of thought without a cause. If they, one after another, have followed Dr. Adam Smith, as boys play "follow my leader," jumping where he jumped, and falling where he fell, it has been that there was a fence where he jumped and a hole where he fell.
The difficulty from which this confusion has sprung is in the pre-accepted 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
