Do you believe that the working classes are going to revolt anytime soon?
The closest thing to rebellion in the rich countries right now are the sporadic suburb riots near Paris and the teabag protests in the USA, not even close, and neither a conduit to communism.
I meet students of marxism in various places in university, they seem to actually believe a revolution is on the horizon, though often a different revolution from person to person.
That belief almost seems religious to me. I admit I have not read Capital. I see the mass population as content and powerless, and easily stremed into various political movements that are unrelated to their actual economic interests, i.e. British National Party.
