Did you find all that in the back of your head? Profit generating enterprise is capitalism, no matter who owns it. State, a collective, shareholders, or your Uncle Joe. It doesn't magically become not capitalism because some of the owners work on the shop floor. And it certainly doesn't become socialism, either!
Cool, don't believe me. Go ahead and start your State Socialism. Let us know how you get on .. from your dorm room at the potato farm in middle Iowa.
Now that's a LOL. Human nature is all the history you need, to know that collectivism at the state level is only possible when it's totalitarian. Every single self-proclaimed socialist not actually living like a socialist (voluntarily) is all the evidence you need that people will only do it if there's a gun pointed at their head. If even SOCIALISTS won't do it, what ****ing chance do you think you have?
We have workplace democracy, because we live in a democracy. You do understand that democracy means freedom of choice, right? None of us are slaves. We can quit a job we're not satisfied with, anytime we like.
