Yeah the problem with your statement here is that we know for a fact that the only thing that stopped capitalism from making people literal serfs is political violence. We had to fight a second Civil War in this country. Literal battles. If it weren't for those you'd be chained to a factory right now. That's the way capitalism will always go. You shouldn't be under misunderstanding that the current level of standard of living has anything to do with capitalism. The Golden Age of capitalism is the Gilded Age.
