Democratic capitalism, also known as capitalist democracy, is a political, economic and social ideology that involves the combination of a democratic political system with a capitalist economic system. It is based on a tripartite arrangement of a private sector-driven market economy based predominantly on a democratic policy, economic incentives through free markets, fiscal responsibility and a liberal moral-cultural system which encourages pluralism. This ideology supports a capitalist economy subject to control by a democratic political system that is supported by the majority. It stands in contrast to authoritarian capitalism by limiting the influence of special interest groups, including corporate lobbyists, on politics.
