The late Bill Niskanen on inequality:
Rawls recognizes that individual well-being is dependent on more than income and wealth, but he does not acknowledge the implications of the fact that the other dimensions of well-being are not fungible. Consider the following example.
One young man is healthy and handsome, spends his days on the beach, has his pick of young women companions, and makes $10,000 a year by busing tables in the evening. Another young man is confined to a wheelchair, has congenital body odor, has never had an intimate relationship, and, with no other life, makes $100,000 a year as an expert computer programmer. In this case, who is worse off? Who should redistribute what to whom and how?
