In his “A Theory of Justice”, Rawls outlines the Difference Principle:
A core component of his theory of justice that permits social and economic inequalities only if they work to the maximum benefit of the least-advantaged members of society (The Precariat).

Rawls assumes that absolute strict equality can reduce total economic output because people may work harder when they keep a larger share of their earnings.
If unequal rewards make the economy richer overall, a portion of that extra wealth can benefit the worst-off.
