Capitalism is a system of property relations and labor relations. It is conceivable to not have those property relations and labor relations in a firm. However, a corporation doesn't do that as the employer solely appropriates the entire positive and negative result of production i.e. the property rights to the produced outputs and liabilities for the used-up inputs. In a worker coop, the workers jointly appropriate the fruits of their labor. Capitalist property relations aren't present @memes
