“...if it is desirable that a person setting to work should not enthralled himself, should not give up part of his labor, his strength, his independence, either temporarily or permanently, to private individuals whose arbitary power will always determine how great that part shall be, then it is necessary that private individuals should control neither the instruments of labor (tools, machines, factories), nor the places of cultivation of raw materials (the earth), nor the raw materials previously stored up, nor the means of storing and transporting them to particular places (the means of communication, warehouses, and so on), nor the means of existence during work (the supplies of the means of subsistence and housing).”
