I guess the main issue is with the government having absolute control over the economy. I would not want the most prominent politicians in my country having control of the economy. No matter how much I dislike capitalism.
Just put the people who work for a company in charge of the company. Have them elect who calls the shots. Also have them directly benefit from the company doing well. I guess that is like end-stage unions or smth. All power to the workers. Should be doable within capitalism, maybe, probably.
