Utopianism, socialism and communism emerged as a reaction against capitalism, an economic system based on the private ownership of the means of production. These three ideologies oppose to capitalism, considered the engine of inequality, since they seek to achieve significant social change in order to live in a better and more equal society where there is not a wealthier class, as opposed to capitalism, which establishes power in the hands of a minority capitalist class through the exploitation of the working class. In that way, the three ideologies support the idea of social progress and stand against the progress of free individuals.
