Final answer:
John Rawls' concept of social contract allows for inequalities only if they benefit the least advantaged in society, as expressed in the Difference Principle from his book A Theory of Justice.
Step-by-step explanation:
In John Rawls' concept of social contract, no one should have more than others unless it is to the greatest benefit of the least advantaged, consistent with the just savings principle, and attached to offices and positions open to all under conditions of fair equality of opportunity. Rawls' idea represents a specific tenet of his theory of justice, which aims to ensure that inequalities in society are permitted only if they work in favor of those with the least advantages. This is described in his influential book, A Theory of Justice, as the Difference Principle.
The Difference Principle posits that inequalities are acceptable only if they result in compensating benefits for everyone, and in particular, for the worst-off members of society. In essence, Rawls is not advocating for a pure egalitarian society where resources are distributed equally, regardless of contribution or need. Instead, he argues for a system where the welfare of the least well-off is improved as a result of the inequality, reflecting his support for a version of a welfare state that seeks to address structural inequalities within society.
