Marx's concept of a post-capitalist communist society involves the free distribution of goods made possible by the abundance provided by automation.[27] The fully developed communist economic system is postulated to develop from a preceding socialist system. Marx held the view that socialism—a system based on social ownership of the means of production—would enable progress toward the development of fully developed communism by further advancing productive technology. Under socialism, with its increasing levels of automation, an increasing proportion of goods would be distributed freely.[28]
