 Changes with regard to features (ii), (iii), and (v) are hotly debated amongst socialists. Regarding (ii), socialists retain the view that workers should control their labor power, but many do not affirm the kind of absolute, libertarian property rights in labor power that would, e.g., prevent taxation or other forms of mandatory contribution to cater for the basic needs of others (G.A. Cohen 1995). Regarding (iii), there is a recent burgeoning literature on “market socialism”, which we discuss below, where proposals are advanced to create an economy that is socialist but nevertheless features extensive markets. Finally, regarding (v), although most socialists agree that, due to competitive pressures, capitalists are bound to seek profit maximization, some puzzle over whether when they do this, it is “greed and fear” and not the generation of resources to make others besides themselves better-off that is the dominant, more basic drive and hence the degree to which profit-maximization should be seen as a normatively troubling phenomenon. (See Steiner 2014, in contrast with G.A. Cohen 2009, discussing the case of capitalists amassing capital to give it away through charity.) Furthermore, some socialists argue that the search for profits in a market socialist economy is not inherently suspicious (Schweickart 2002 [2011]). Most socialists, however, tend to find the profit motive problematic.
