 That last point may be too quick, however, for there are other indirect ways in which private property contributes to freedom (Purdy 2005). Milton Friedman (1962) argues that political liberty is enhanced in a society where the means of intellectual and political production (printing presses, photocopying machines, computers) are controlled by a number of private individuals, firms, and corporations—even if that number is not very large. In a capitalist society, a dissident has the choice of dealing with several people (other than state officials) if he wants to get his message across, and many of them are prepared to make their media available simply on the basis of money, without regard to the message. In a socialist society, by contrast, those who are politically active either have to persuade state agencies to disseminate their views, or risk underground publication. More generally, Friedman argues, a private property society offers those who own nothing a greater variety of ways in which they earn a living—a larger menu of masters, if you like—than they would be offered in a socialist society. In these ways, private property for some may make a positive contribution to freedom—or at least an enhancement of choice—for everyone.
