The "revisionist" reformers were wiser than Marx in that the established order evolves over time instead of being held firmly in place by a conspiring, ruling class of elites until they are usurped in a violent revolution. With all due respect I would also state that socialists who still retain faith in the primacy of class struggle and the allocation of economic capital in explaining all of the problems of society have their heads shoved woefully far up their asses. I do respect Marx as a bold thinker and a great contributor to the social sciences, but not all of his ideas aged well.
Capital is not personal.A fair correction, ya. Nonetheless, I consider capital to be divided into symbolic, cultural, social, and economic flavors in the Bourdieuan interpretation of Neo-Weberian thought, and look at social conflict and all hierarchical arrangements among people that ensue as impossible to fully remove from society. The Marxist's fixation on economic capital overlooks the importance of symbols, domains, and strategic conversions of capital. I would argue that a classless society is possible in popular perception only - not in reality - that all means of production can never truly be owned or controlled in common for sole use in advancing the People's interests. Revolutions, at least so far as I am aware, can only ever replace an arrangement of hierarchies and institutions with another.
