In the form of interest, the entire surplus above the barest means of subsistence (the amount that later becomes wages of the producers) can be consumed by usury (this later assumes the form of profit and ground-rent), and hence it is highly absurd to compare the level of this interest, which assimilates all the surplus-value excepting the share claimed by the state, with the level of the modern interest rate, where interest constitutes at least normally only a part of the surplus-value. Such a comparison overlooks that the wage-worker produces and gives to the capitalist who employs him, profit, interest and ground-rent, i.e., the entire surplus-value. Carey makes this absurd comparison in order to show how advantageous the development of capital, and the fall in the interest rate that accompanies it, are for the labourer. Furthermore, while the usurer, not content with squeezing the surplus-labour out of his victim, gradually acquires possession even of his very conditions of labour, land, house, etc., and is continually engaged in thus expropriating him, it is again forgotten that, on the other hand, this complete expropriation of the labourer from his conditions of labour is not a result which the capitalist mode of production seeks to achieve, but rather the established condition for its point of departure. The wage-slave, just like the real slave, cannot become a creditor's slave due to his position — at least in his capacity as producer; the wage-slave, it is true, can become a creditor's slave in his capacity as consumer. Usurer's capital in the form whereby it indeed appropriates all of the surplus-labour of the direct producers, without altering the mode of production; whereby the ownership or possession by the producers of the conditions of labour and small-scale production corresponding to this — is its essential prerequisite; whereby, in other words, capital does not directly subordinate labour to itself, and does not, therefore, confront it as industrial capital — this usurer's capital impoverishes the mode of production, paralyses the productive forces instead of developing them, and at the same time perpetuates the miserable conditions in which the social productivity of labour is not developed at the expense of labour itself, as in the capitalist mode of production.
