“The class struggle which, according to Marxists is one of the fundamental contradictions of capitalism, is ultimately based, according to Marxism, on the division of society between the owners of the means of production and the proletarians who do not own the means of production, and have to sell their labour power to the capitalists. In order to overcome this contradiction, Marxists advocate the socialisation of the means of production. In the traditional model, socialisation is identified primarily with state ownership.”
