“…political elites are defined as persons who, by virtue of their strategic locations in large or otherwise pivotal organizations and movements, are able to affect political outcomes regularly and substantially. The elites have power over the state, the civil organization of political power. Even though they could have conflicts with the mass, which certainly can affect political decisions from “top down” to “bottom up” the possession of multiples forms of capital (social, cultural, economic, politic, or any other social benefits derived from the preferential treatment and cooperation between individuals and groups) allows [them] to ensure their social reproduction as well as the cultural reproduction of the ruling class.” Elites, political elites and social change in modern societies; REVISTA DE SOCIOLOGÍA, Nº 28 (2013) pp. 31-49.
