"The great principle underlying the present system is unpaid labor. Those who amass fortunes, build palaces, and live in luxury, are doing that by virtue of unpaid labor. Being directly or indirectly the possessors of land and machinery, they dictate their terms to the workingman. He is compelled to sell his labor cheap, or to starve. The price paid him is always far below the real value. He acts under compulsion, and they call it a free contract. This infernal state of affairs keeps him poor and ignorant; an easy prey for exploitation."
