Final answer:
Stalin and Mussolini disagreed on ownership of property, with Stalin advocating for state ownership under communism, and Mussolini allowing private ownership in a fascist framework.
Step-by-step explanation:
Joseph Stalin and Benito Mussolini disagreed on the subject of ownership of property. Stalin, representing the Soviet Union under the communist ideology, advocated for the state ownership of the means of production, which is a hallmark of communism. In this system, the state sets wages, regulates production, and controls prices. Conversely, Mussolini, who established a fascist dictatorship in Italy, allowed for private ownership of property. Unlike communism, fascism does not seek to end capitalism but rather works with it while enforcing strong nationalism and authoritarian rule.
