Universities that want to improve their selection procedures by identifying talented people (of any colour or creed) from disadvantaged backgrounds should be encouraged. But selection on the basis of race is neither a fair nor an efficient way of doing so. Affirmative action replaced old injustices with new ones: it divides society rather than unites it. Governments should tackle disadvantage directly, without reference to race. If a school is bad, fix it. If there are barriers to opportunity, remove them. And if Barack Obama’s daughters apply to a university, judge them on their academic prowess, not the colour of their skin.
