Why *don't* the proles revolt? After all, capitalism is way past its "use-by" date by now. That's demonstrated on this list daily by the countless, excellent news articles posted.
Could this condition originate in a conservative psychological character structure rooted in the upbringing of individuals within societies where the monogamous-paternalistic family, private property and the State permeate social relations?
Or, if you want to take it further, there's Judith Butler's argument - rooted in that silly doctrine called psychoanalysis - that subjects are formed in subjection (through deference to authority figures, like parents, and their successors, like language and law), and that attitude of deference to authority persists through life, for fear of the disintegration of the subject.
