Berquist author Jon L (2015) states that "politicians and business leaders not only create policies that affect the institutions of others, but also socialize together, share loyalty to the same schools. , join the same clubs, attend the same functions and contribute to the same causes. Furthermore, members of the power elite possess significant personal resources in addition to their control over larger societal resources” (p. 1). Another distinction between Marxist, pluralist and elitist theories is that both pluralist and Marxist theories are driven by structural functionalism and they both have specific functions in society while the elite are not controlled by groups of interest. According to the authors, “the existence of elites does not necessarily cancel out the impact of interest groups” (p. 74). Although there are clearly some distinctions in the theories, they have few similarities. Both Marxist and elite theories believe that power is controlled by smaller entities, and both exploit people. Author Susan et al (2013) state that “the pluralist model and elite…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 the three theories is to cause inequalities between members of society, which leads to conflicts. Helping professionals such as social workers must find ways to champion the human cause.
