interest as signifying that part of the produce which goes to capital.
To recapitulate:
Land, labor, and capital are the factors of production. The term land includes all natural opportunities or forces; the term labor, all human exertion; and the term capital, all wealth used to produce more wealth. In returns to these three factors is the whole produce distributed. That part which goes to land owners as payment for the use of natural opportunities is called rent; that part which constitutes the reward of human exertion is called wages; and that part which constitutes the return for the use of capital is called interest. These terms mutually exclude each other. The income of any individual may be made up from any one, two, or all three of these sources; but in the effort to discover the laws of distribution we must keep them separate.
Let me premise the inquiry which we are about to undertake by saying that the miscarriage of political economy, which I think has now been abundantly shown, can, it seems to me, be traced to the adoption of an erroneous standpoint. Living and making their observations in a state of society in which a capitalist generally rents land and hires labor, and thus seems to be the undertaker or first mover in production, the great cultivators of the science have been led to look upon capital as the prime factor in production, land as its instrument, and labor as its agent or tool. This is apparent on every page—in the form and course of their reasoning, in the character of their illustrations, and even in their choice of terms. Everywhere capital is the starting point, the capitalist the central figure. So far does this go that both Smith and Ricardo use the term "natural wages" to express the minimum upon which laborers can live; whereas, unless injustice is natural, all that the laborer produces should
