Mary Edna Tobias Marcy, Shop Talks on Economics — How Profits are Made (1911)
“ For the things he gets for his labor-power contain only two hours of labor, while the things he produces, and which are claimed by the capitalist, contain ten hours of labor. The miner sells his labor-power and, naturally, the capitalist desires to use it as profitably (for himself) as possible. If the wage-worker demanded commodities in exchange for his products, containing an equal quantity of labor, he would no longer be a wage-worker, for capitalists would no longer employ him. There would be nothing—no surplus value—left for the capitalists. ”
