“Recent statistics show that in 1920 (ha!) there were in the United States over 41 million persons of both sexes engaged in gainful occupations out of a total population of over 105 million. Out of those 41 million only 26 million were actually employed in the industries, including transportation and agriculture, the balance of 15 million consisting mostly of persons engaged in trade, of commercial travelers, advertisers, and various other middlemen of the present system. In other words, 15 million person would be released for useful work by a revolution in the United States. A similar situation, proportionate to population, would develop in other countries. […] Capitalist production is for profit; more labor is used today to sell things than to produce them”
