Yeh basically. I was being kinda flippant with my comment but capitalism evolved because the means of production developed to the point where it was much more productive than feudalism. Marx himself says that the reason capitalism toppled feudalism is because it is superior to feudalism. It’s the same reason we say “communism will win”, not because of some moralist view of the world, just that communism is the inevitable next revolution in production. Unless of course the class struggle ends in the “mutual ruin of all classes” as Marx put it.
