One societal group (class) owned and controlled the means of production, while another societal class worked the means of production; in the relations of production of that status quo, the goal of the owner-class was to economically benefit as much as possible from the labour of the working class. Moreover, in the course of economic development, when a new type of economy displaced an old type of economy—agrarian feudalism superseded by mercantilism, in turn superseded by the Industrial Revolution—the rearranged economic order of the social classes favored the social class who controlled the technologies (the means of production) that made possible the change in the relations of production. Likewise, there occurred a corresponding rearrangement of the human nature (Gattungswesen) and the system of values of the owner-class and of the working-class, which allowed each group of people to accept and to function in the rearranged status quo of production-relations.
