The first problem is that the alternative is far less fair. Humans are hundreds of times more biased than algorithms. Judges give much harsher sentences after they have eaten lunch. Ugly people are discriminated against far more than attractive people. People of different political affiliations are discriminated against more than race is. And when asked to make predictions about candidates, we are only barely better than random (but think we are much better.) The second is that unfairness isn't a problem. Whatever has the most utility should be preferred. If one person is worse off and 99 are better off, it's a net good.
