Economic dictatorship may be domestic or international, comprising economic imperialism, oligopoly and monopoly under a market system, and government economic intervention or control. Economic imperialism and the activities of multinational companies may lead to foreign debt, foreign control and influence, and possibly to national disintegration. Monopoly, oligopoly and government intervention may lead to a high cost of living, inefficiency, unequal distribution of wealth and the bankruptcy of small and medium-sized firms. State controlled economies are often synonymous with political dictatorship.
