Overview#Social Justice is a concept of fair and just relations between the individual and society, as measured by the distribution of wealth, opportunities for personal activity, and social privileges.
F A Hayek:
Social Justice is the that the state ought to treat all people equally in spite of the fact that they are very unequal.
You can't deduce from this they who that because a people are unequal the state also treats them unequally in order to make them equal and that what social justice amounts to.
It's a demand that the state should treat the different people differently in order to place them in the same position the rule of equal treatment applies only those things the state has to do in any case but to make making people equal a goal of governmental policy would force government to treat people very unequal.
