"It is largely irrelevant whether the propertied elite acquires managerial skills, takes an active part in managing corporate enterprise, or has assimilated non-propertied elite manager into its own class and interests. What Mills and his disciple, William G. Domhoff and their school do not sufficiently perceive or appreciate thoroughly is that the interest of the propertied elite have changed substantially with the revolution of mass and scale. The propertied elite or “grand bourgeosie” of the bourgeois order may not have changed significantly in family composition, and certainly it retain wealth and status. Its economic interests, however, have changed from being vested in the hard property of privately owned and operated entrepreneurial firms, usually comparatively small in scale, to being intertwined with and dependent upon the de-materialized property of publicly owned, state-integrated, managerially operated mass corporations."
