 Some philosophers have offered arguments to the effect that the government should provide certain goods, independently of whether or not they could be produced in sufficient quantities by the market. Michael Waltzer and Elizabeth Anderson have argued that the sphere of the market should be limited because market norms do not embody certain important values and market exchange may undermine ideals and interests legitimately protected by the state (Walzer 1983, Anderson 1993). According to Anderson, market norms have the following five features: they are impersonal (independent of the relationship and of the other party’s ends), egoistic (the goal is to satisfy one’s personal interests), exclusive (defined as above), want-regarding (as opposed to responsive to objective needs), and oriented to “exit” rather than “voice” (rather than voicing one’s complaint one seeks an alternative) (see Anderson 1993: 143–4).
