South American adherents of democratic socialism, a political philosophy supporting political democracy within a socially owned economy, with a particular emphasis on economic democracy, workplace democracy and workers' self-management within a market socialist economy or some form of a decentralised planned socialist economy. Democratic socialists argue that capitalism is inherently incompatible with the values of freedom, equality and solidarity and that these ideals can only be achieved through the realisation of a socialist society. Although most democratic socialists seek a gradual transition to socialism, democratic socialism can support either revolutionary or reformist politics as means to establish socialism. As a term, democratic socialism was popularised by social democrats and other socialists who were opposed to the authoritarian socialist development in Russia and elsewhere during the 20th century.
