The theory of justice

This article presents the general structure of the question justice in society, its three polar cases which relate to the benefits from the human resources, their difficulties with Pareto-efficiency, and the solutions of these dilemma, notably for the central case where individuals a priori own only their consumptive capacities. This solution is a multidimensional maximin which leads to super-equity (no individual prefers any average of the individuals' allocations to his own). The properties of efficient super-equity are then shown: limits to the dispersion of incomes and relations with equal income, preference to all equal allocations, determination of the redistributive tax-subsidies, relations with other principles. Finally, the efficient implementation of standard ethical positions consists of the equalizing redistribution of incomes earned during a fixed duration while the other earned incomes are untaxed.
