Some do not see it as a problem, arguing that, in the absence of artificial impediments to social mobility, inequality basically reflects differences in talents and choices. They believe that the most talented, thrifty and industrious prosper, even when handicapped by initially adverse social conditions. In a world in which market participants receive a compensation which is in line with their contribution to society (their marginal productivity), the prosperity of the “fittest” cannot be deemed to be unjust and should not be a policy concern. According to this view, strategies to reduce inequality would undermine the power of the market mechanism to generate the most efficient outcomes, because they would reduce incentives to engage in the economic process. Government intervention aimed at ensuring more equality or social justice would, paradoxically, lead to an unfair result by delinking the distribution of rewards from individuals’ contributions to the generation of global income. Public authorities should provide “equality of opportunities”, particularly in the sense that rules should be the same for all individuals, with no barriers or advantages artificially created or distributed.
