It would be manifestly as unjust for the constructors of the plant to compel the operators to pay them over and over again, as it would be for the operators of the machine, having supplied the community with shoes, to demand payment over and over without making another shoe. The shoes will wear out, so will the machines. It is as unreasonable for the first class of laborers to compel the operators of their machinery to keep the same in repair, as for the operators to compel their customers to keep their shoes in perfect condition. For the first laborers to receive a new payment they must build a new plant, and for the operators to receive a new payment they must make new shoes. The confusion of ideas comes in when there intervenes a third party between these two classes of laborers. This third party meets the demands of the class of laborers who build the plant and machines, from hoarded wealth, and then exacts payment from those who operate it. This is then called productive capital, but it is no more productive than the money in the bank vault. The producing, so called, is but the exacting of a part of that which the operators produce. It is the exacting of payment that never pays. The operators are compelled to be forever buying, yet the plant is never bought. The capitalist is forever selling, yet the plant is never sold. Usually, the usurer is a fourth party that stands yet behind the third party, taking no risks, demanding complete security for his loan and also an increase out of the products of the operators. The third party assumes all care and guarantees against all losses and depends for his compensation on a portion of the product after the demands of the fourth party are satisfied. This third party may be an active producer. All that he receives may be fully earned in care, oversight and management of the business of the plant. But the fourth party can have no claim for his services, he has no part in the production. The absurdity, the figment that his capital is productive, is introduced to cover the evident fraud of appropriating, without compensation, a portion of the products of the operators. He has no more claim to an increase of his capital year by year and a doubling in a term of years, than the laborers who built it have to the same plant, perfect and unworn at the end of a term, and in addition, another plant equal in every respect. They built but one, they have no claim upon a second. For the usurer, who takes their place, to double his wealth, and yet the debt be undischarged, is a flagrant fraud.
