I'm not against classifying "modes of production." I'm simply against the long and tedious tradition of trying to claim that one mode automatically causes another mode to follow it.
Capitalism certainly _suggests_ socialism, but it itself does nothing but work against it. Feudalism (a weak form of empire), likewise, leaves room for merchant power, but that's merely one aspect of the story. If Europe hadn't inherited Eurasian technologies and hadn't had the "New World" to plunder, capitalism might never have happened.
