Government is used to impose agendas that result from the symbiotic relationship between the neoconservative ideology of US world hegemony and the economic interests of powerful private interest groups, such as Wall Street, the military/security complex, the Israel Lobby, agribusiness, and extractive industries (energy, mining, and timber). Dollar imperialism, threats, bribes, and wars are means by which US hegemony is extended. These agendas are pursued without the knowledge or approval of the American people and in spite of their opposition.
Professor Martin Gilens at Princeton University and Professor Benjamin Page of Northwestern University have examined American governance and have concluded that the US is an oligarchy ruled by powerful rich private interest groups and that the US government has only a superficial resemblance to a democracy. Their analysis is forthcoming in publication in the journal, Perspectives on Politics.
