- Rawls says some inequalities are permissible or perhjaps even required for a society to be, for example, productive. 1.Principle of equal liberty: each person has an equal right to the most extensive liberties compatible with similar liberties for all � we�d all want the most extensive liberties compatible with similar liberties for all. (equal basic liberties) 2.Social and economic inequalities should be arranged so that they are both (a) to the greatest benefit of the least advantaged persons (difference principle), and (b) attached to offices and positions open to all under conditions of equality of opportunity (equality of opportunity, principle) rawls argues that social and economic inequalities should be arranged so that it�s to the greatest benefit of the least advantaged. the diufference principle is a way of working out- when inequalitiesa are permissible but what social and economic inequalities are okay then? One example is inequalities in wages which are required to create incentives for people to go into socially valuable professions. In saying that, if rawls is such an egalitarian, why has he given us a principle that is all about having inequalities? So normative value of equality: rawls seems to be giving us an argument having potential inequalities: an inequality could be justified if is to the greatest advantage of the least advantaged.
