So, the only power network of any consequence in the history of the United States has been the economic one, which under capitalism generates a business-owning class and a working class, along with small businesses and skilled craft workers who are self-employed, and a relatively small number of highly trained professionals such as architects, lawyers, physicians, and scientists. In this context, the key reason why money can rule — i.e., why the business owners who hire workers can rule — is that the people who work in the factories and fields were divided from the outset into free and slave, white and black, and later into numerous immigrant ethnic groups as well, making it difficult for workers as a whole to unite politically to battle for higher wages and better social benefits. This important point is elaborated on toward the end of this document in a section entitled “The Weaknesses of the Working Class.” Moreover, the simple answer that money rules has to be qualified somewhat. Domination by the few does not mean complete control, but rather the ability to set the terms under which other groups and classes must operate. Highly trained professionals with an interest in environmental and consumer issues have been able to couple their technical information and their understanding of the legislative process with timely publicity to win governmental restrictions on some corporate practices. Wage and salary workers, when they are organized or disruptive, sometimes have been able to gain concessions on wages, hours, and working conditions. Most of all, there is free speech and the right to vote. While voting does not necessarily make government responsive to the will of the majority, under certain circumstances the electorate has been able to place restraints on the actions of the wealthy elites, or to decide which elites will have the greatest influence on policy.
