 Another market socialist model, proposed by Carens (1981, 2003), does not impose worker self-management. The Carensian model mirrors the current capitalist system in most respects while introducing two key innovative features. First, there would be direct governmental provision regarding certain individually differentiated needs (via a public health care system, for example). Second, to access other consumption goods, everyone working full time would get the same post tax income. Pre-tax salaries would vary, signaling levels of demand in the market. People would choose jobs not only on the basis of their self-regarding preferences, but also out of a sense of social duty to use their capacities to support others in society. Thus, honoring the Abilities / Needs Principle, they would apply for jobs (within their competencies) in which the pre-tax income is relatively high. If it worked, this model would recruit the efficiency of markets, but it would not involve the selfish motives and inegalitarian outcomes typically linked to them in capitalism.
