@mk @adamosophy @realcaseyrollins when most leftists speak of capitalism they are referring to control of society by those with large amounts of capital, while socialism refers to direct ownership of the means of production by the workers, often socialism is assumed to include the abolition of wages, and possibly money as a whole.
However, when speaking of worker ownship of the means of production, that certainly can be down in a decentralized manner (i.e. the workers who own FIAT contributing their products to the workers'market, while the workers that own GM can create their own and see what happens to be preferred, and listen to price signals to consider future production. 100 years ago socialists where pretty evenly split between centralizers versus de-centralizers, while today most folks who call themselves socialists are centralizers, there are those of us, like most libertarian socialist, who would say otherwise.
