History says otherwise. What if no one wants to work in the commune or too few to support the commune?
Nothing is about Capitalism except Capitalism, it doesn't care about anything but itself and the accumulation of wealth. The belief that social good arises from Capitalism intrinsically was never part of the Wealth of Nations (which required government oversight) and has been debunked, even social capitalism is an experiment to get back to what Capitalism was supposed to be but it's far from there and probably won't get there without more government regulation.
