The document discusses John Rawls' theory of justice as fairness. It explains that under the original position, people behind a veil of ignorance would agree to two principles: 1) Equal liberty for all and 2) Social and economic inequalities must benefit society's least well-off and arise from fair equality of opportunity. The difference principle holds that redistribution of wealth is justified if it improves the situation of the worst-off group. The document provides a simplified example comparing utilitarian, egalitarian, and Rawlsian approaches to distributing resources between two people.
