Analogous to the class of the major capitalists, other modes of production give rise to different ruling classes: under feudalism it was the feudal lords while under slavery it was the slave-owners. Under the feudal society, feudal lords had power over the vassals because of their control of the fiefs. This gave them political and military power over the people. In slavery, because complete rights of the person's life belonged to the slave owner, they could and did every implementation that would help the production in the farm.
In his recent studies on elites in contemporary societies, Mattei Dogan has argued that because of their complexity and their heterogeneity and particularly because of the social division of work and the multiple levels of stratification, there is not, or can not be, a coherent ruling class, even if in the past there were solid examples of ruling classes as in the Russian and Ottoman Empires and the more recent totalitarian regimes of the 20th century (Communist and Fascist).
Milovan Djilas said that in a Communist regime the nomenklatura form a ruling class, which "benefited from the use, enjoyment, and disposition of material goods", thus controls all of the property and thus all of the wealth of the nation. Furthermore, he argued, the Communist bureaucracy was not an accidental mistake, but the central inherent aspect of the Communist system since a Communist regime would not be possible without the system of bureaucrats.
Globalization theorists argue that today a transnational capitalist class has emerged.
