Furthermore, members of the ruling elite possess extensive personal resources in addition to control over broader social resources” (p. 1 ).Another distinction between Marxist, pluralist and elite theory is that pluralist and Marxist theories are guided by structural functionalism and both have specific functions in society while the elite is not controlled by interest groups authors “the existence of elites does not necessarily nullify the impact of the interest group” (p. 74). Although there are clearly some distinctions in the theories, they have few similarities. Marxist and elite theories believe that power is controlled by entities smaller, both exploit people. The author Susan et al (2013) state that “Pluralist and Elite Model… We believe that these are not incompatible but rather different aspects of the same reality” (p. 74). Marxist and pluralist theorists also agree that the ruling class is motivated by political and economic power. The most important function of all three theories is that they cause inequalities between people in society which results in conflicts.
