Market socialism does not fully satisfy socialist standards of distributive justice, but it scores far better by those standards than market capitali… - Gerald Cohen

I believe that certain inequalities that cannot be forbidden in the name of socialist equality of opportunity should nevertheless be forbidden, in the name of community. But is it an injustice to forbid the transactions that generate those inequalities? Do the relevant prohibitions merely define the terms within which justice will operate, or do they sometimes (justifiably?) contradict justice? I do not know the answer to that question.

The technology for using base motives to productive economic effect is reasonably well understood. Indeed, the history of the twentieth century encourages the thought that the easiest way to generate productivity in a modern society is by nourishing the motives of which I spoke earlier, namely, those of greed and fear. But we should never forget that greed and fear are repugnant motives. Who would propose running a society on the basis of such motives, and thereby promoting the psychology to which they belong, if they were not known to be effective, if they did not have the instrumental value which is the only value that they have?

Whereas many socialists have recently put their faith in market socialism, nineteenth-century socialists were, by contrast, for the most part opposed to market organization of economic life. The mainstream socialist pioneers favored something that they thought would be far superior, to wit, comprehensive central planning, which, it was hoped, could realize the socialist ideal of a truly sharing society. And the pioneers' successors were encouraged by what they interpreted as victories of planning, such as the industrialization of the Soviet Union and the early institution of educational and medical provision in the People's Republic of China. But central planning, at least as practiced in the past, is, we now know, a poor recipe for economic success, at any rate once a society has provided itself with the essentials of a modern productive system.
