The power structure in society is an essential part of understanding sociology. The two main theories that differentiate this structure are Mills's theory of a power elite and Riesman's contrasting theory of veto groups, or pluralism. The two theories are often found to varying degrees when considering important public decisions, such as the Hoover Redevelopment Plan or the University Village Plan. Generally, one of these theories is more applicable and relevant to certain public decisions and developments depending on the issue. Although both of these theories played a role in the Hoover Redevelopment Plan and the University Village Plan, power elite theory is ultimately more responsible for instituting these developments. The premise of Mills' theory revolves around a group at the top of the hierarchy. called the power elite. This is a group made up of military officials, senior government officials and senior business executives. Behind this authoritarian group is a middle class, or intermediate level of power. These are the people who work in Congress and other mid-level interest groups. Below them are the masses, a group that possesses little or no power in society and is essentially manipulated by those above them. The ruling elite makes all important public decisions, especially those concerning foreign policy. The ruling elite is united not only because of their common desire for wealth and domination, but also because of their mutual religious beliefs, education, and other social interests within their institutions. If we accept this theory of a small, all-powerful governing force, then democracy in society would either be very weak or non-existent.

A coalition known as UNIDAD (United Neighbors In Defense Against Displacement) has been heavily involved in this issue. Residents feared that after a drastic renovation of the neighborhood, their rents would increase exponentially, forcing them to look for more affordable housing options elsewhere. Although USC offered a $2 million contribution to aid public housing, UNIDAD demanded a minimum of $20 million, temporarily delaying the start of the project. USC agreed to respond to their requests, thereby satisfying both parties involved. This example of residents and UNIDAD members defending their interests is an example of a veto group. The decision and implementation of this plan, however, indicate that the ruling elite exercises control, but in a more democratic way..
