  Another thought that motivates the family of equality-of-resources ideals is that society's obligations by way of providing for its members are limited. A just and egalitarian society is not plausibly held to be obligated to do whatever turns out to be necessary to bring it about that their members attain any given level or share of quality of life. The reason for this is that the quality of life (the degree to which one attains valuable agency and well-being goals) that any individual reaches over the course of her life depends on many choices and actions taken by that very individual, so to a considerable extent, the quality of life one reaches must be up to oneself, not the job of society or some agency acting on behalf of society. Along these lines, the actual course of an individual's life and the degree of fulfillment it reaches also depend on many chance factors for which nobody can reasonably be held accountable. Justice is a practical ideal, not a Don Quixote conception that aims to correct all bad luck of any sort that befalls persons. A reasonable morality understands the social justice obligations of society as limited, not open-ended and unbounded. So if equality of condition is part of social justice, it too must reflect an appropriately limited conception of social responsibility. Equality of resources fills this bill.
