Critics of capitalism argue that it concentrates power in the hands of a minority capitalist class that exists through the exploitation of the majority working class and their labor, prioritizes profit over social good, natural resources and the environment, is an engine of inequality, corruption and economic instabilities, and that many are not able to access its purported benefits and freedoms, such as freely investing. Supporters argue that it provides better products and innovation through competition, promotes pluralism and decentralization of power, disperses wealth to people who are able to invest in useful enterprises based on market demands, allows for a flexible incentive system where efficiency and sustainability are priorities to protect capital, creates strong economic growth and yields productivity and prosperity that greatly benefit society.
