The capitalist apparatus requires emmense effort to maintain. Military, police, propaganda, bailouts,… Its not self sustaining and its not natural. For comparison, cooperative, democratically controlled workplaces, have greater survival rates than their conventional, privately owned firms. Not to mention workers or more likely paid a living wage, have greater job stability and satisfaction, and just as likely, if not more so to lead to innovation. Its literally proven a better economic system, but yet some still think it offers empty promises.
