"Socialism and Capitalism: Are They Qualitatively Different Socioeconomic Systems?", by Kotz, David M. Retrieved February 19, 2011, from University of Massachusetts: http://people.umass.edu/dmkotz/Soc_and_Cap_Diff_Syst_06_12.pdf: "This understanding of socialism was held not just by revolutionary Marxist socialists but also by evolutionary socialists, Christian socialists, and even anarchists. At that time, there was also wide agreement about the basic institutions of the future socialist system: public ownership instead of private ownership of the means of production, economic planning instead of market forces, production for use instead of for profit."
