apathy and frustration took their inevitable toll, and they would always have been susceptible to growing inequities and inefficiencies as the effects of differential economic power grew. Under central planning neither planners, managers, nor workers had incentives to promote the social economic interest. Nor did impending markets for final goods to the planning system enfranchise consumers in meaningful ways. But central planning would have been incompatible with economic democracy even if it had overcome its information and incentive liabilities. And the truth is that it survived as long as it did only because it was propped up by unprecedented totalitarian political power". Critique of public enterprise Slow or stagnant technological advance Economist Milton Friedman argued that socialism, by which he meant state ownership over the means of production, impedes technological progress due to competition being stifled. He noted that "we need only look to the United States to see where socialism fails" by observing that the "most technologically backward areas are those where government owns the means of production". Friedman claimed that socialism advocated the abolition of a free markets and money- and risk-based reward systems, a claim disputed by some socialists. Friedman argues that without such a money- and risk-based reward system, many capitalist inventors, whom Friedman holds would nonetheless exist within socialism, would not risk time or capital for research. Friedman believed that this was one of the reasons for the United States patent system and copyright law, arguing: Socialism has proved no more efficient at home than abroad. What are our most technologically backward areas? The delivery of first class mail, the schools, the judiciary, the legislative system—all mired in outdated technology. No doubt we need socialism for the judicial and legislative systems. We do not for mail or schools, as has been shown by Federal Express and others, and by the ability of many private schools to provide superior education to underprivileged youngsters at half the cost of government schooling. [...] We all justly complain about the waste, fraud and inefficiency of the military. Why? Because it is a socialist activity—one that there seems no feasible way to privatize. But why should we be any better at running socialist enterprises than the Russians or Chinese? By extending socialism far beyond the area where it is unavoidable, we have ended up performing essential government functions far less well than is not only possible but than was attained
