developed the theory of the state as a neutral arena for contending interests or its agencies as simply another set of interest groups. With power competitively arranged in society, state policy is a product of recurrent bargaining. Although pluralism recognizes the existence of inequality, it asserts that all groups have an opportunity to pressure the state. The pluralist approach suggests that the modern democratic state's actions are the result of pressures applied by a variety of organized interests. Dahl called this kind of state a polyarchy. Pluralism has been challenged on the ground that it is not supported by empirical evidence. Citing surveys showing that the large majority of people in high leadership positions are members of the wealthy upper class, critics of pluralism claim that the state serves the interests of the upper class rather than equitably serving the interests of all social groups. Contemporary critical perspectives Jürgen Habermas believed that the base-superstructure framework, used by many Marxist theorists to describe the relation between the state and the economy, was overly simplistic. He felt that the modern state plays a large role in structuring the economy, by regulating economic activity and being a large-scale economic consumer/producer, and through its redistributive welfare state activities. Because of the way these activities structure the economic framework, Habermas felt that the state cannot be looked at as passively responding to economic class interests. Michel Foucault believed that modern political theory was too state-centric, saying "Maybe, after all, the state is no more than a composite reality and a mythologized abstraction, whose importance is a lot more limited than many of us think." He thought that political theory was focusing too much on abstract institutions, and not enough on the actual practices of government. In Foucault's opinion, the state had no essence. He believed that instead of trying to understand the activities of governments by analyzing the properties of the state (a reified abstraction), political theorists should be examining changes in the practice of government to understand changes in the nature of the state. Foucault developed the concept of governmentality while considering the genealogy of state, and considers the way in which an individuals understanding of governance can influence the function of the state. Foucault argues that it is technology that has created and made the state so elusive and successful, and that instead of looking at the state as something to be toppled
