Malgariya, I do not adhere to Marx's words as dogmas but I would say that almost all of the themes of Marx, Engels and Lenin's works such as Capitalist Monopolies, Anarchy of Production, the Materialist interpretation of History, the Capitalist-Worker dynamic and Imperialism as a direct consequence of Capitalism stand true even today.
Non-industrialized, rural world? What are you talking about? Even in Pakhtunkhwa, the feudal class is now subservient to the industrialists. They have a symbiotic relationship. I do not quite understand what 'neo-Marxist' is or what to you add/deduct from Marxist thought and why?
