I saw this on affirmative action, and thought of Carl Cohen's review of Thomas Sowell's Affirmative Action Around the World: An Empirical Study:

• Politicians buy support by confirming preferences and extending them to more and more ethnic groups. Enlargement is the easiest course. Race preference does not wind down; it winds up. Proliferation is the rule.


• The inferior performance of some ethnic groups is not always a consequence of discrimination against them. On the contrary, even the imposition of discriminatory advantages favoring a majority cannot obscure the fact that some groups prove less competent than others.


• Preferences promote racial conflict.
