You're taking them out of context. Marx didn't want revolution for revolution's sake. He had a specific change to the social order in mind, namely the cause of socialism. He wouldn't approve of the US.
So you're saying that the Women's Suffrage movement changed nothing? The Civil Rights movement didn't have any effect? The Sexual Revolution did little? What about the unions? I can go on. Are you saying that none of our bloodless revolutions made any changes to the social order?
