They who talk about abolishing interest fall into an error similar to that previously pointed out as giving its plausibility to the doctrine that wages are drawn from capital. When they thus think of interest, they think only of that which is paid by the user of capital to the owner of capital. But, manifestly, this is not all interest, but only some interest. Whoever uses capital and obtains the increase it is capable of giving receives interest. If I plant and care for a tree until it comes to maturity, I receive, in its fruit, interest upon the capital I have thus accumulated—that is, the labor I have expended. If I raise a cow, the milk which she yields me, morning and evening, is not merely the reward of the labor then exerted; but interest upon the capital which my labor, expended in raising her, has accumulated in the cow. And so, if I use my own capital in directly aiding production, as by machinery, or in indirectly aiding production, in exchange, I receive a special and distinguishable advantage from the reproductive character of capital, which is as real, though perhaps not as clear, as though I had lent my capital to another and he had paid me interest.
