"John Rawls believes that every member of a society should enjoy equal liberties. He believes that a society can be just and fair only if all members enjoy equal freedom. At the very least, a just society must ensure that all of its members start out on equal footing. A good society should make sure that the least advantaged members receive the greatest benefits. The highest priority should be to serve the most disadvantaged member. The interests of the most advantaged member of society should be government's lowest priority."
