“What Inequality Does” critiques the idea of promoting diversity and equality as ultimate societal values. It argues that when diversity is pursued for its own sake, without consideration for moral or practical distinctions, it can undermine social cohesion and economic progress. The author distinguishes between inherent, beneficial diversity (linked to specialization) and diversity celebrated for its own sake, suggesting that diversity celebrated for its own sake leads to irrational outcomes not the least of which is equality between the righteous and the profane. Diversity is not a human right.
