Equality does not matter. Without further context, the mere fact of equality or inequality has zero moral implications. What actually matters is justice. When people talk about the importance of equality, they’re trying to talk about justice, but they’re doing so imprecisely.
It is obvious that different people should be treated differently. A high-achieving student should be given admission to a prestigious college, while a mediocre student should not. To treat the two students equally would, in fact, be unjust. Give to each what he is owed. Through her achievements, the high-achieving student has demonstrated that she is owed something which the mediocre student is not.
There are many ways in which you can be owed something. Personal merit is one of these ways. Another way is by being wronged. If someone steals from you, then they owe you what they stole from you. You can also be owed something by entering into and fulfilling your side of a voluntary exchange with another person. I work for my employer, and as a result, they owe me my salary.
Certain people would have us believe that unequal outcomes between groups are prima facie evidence of injustice. These people are relying on our failure to properly distinguish equality and justice to further their political agenda. A good example of this is the so-called wage gap. We are told that the average woman makes 77 cents per hour for every dollar per hour the average man makes, the implication being that we’re a misogynistic society that values female labor less than male labor. In reality, this gap is more reasonably explained by how women, on average, are less motivated in their career choices by salary than are men, on average, as well as by how women, on average, are more agreeable and therefore less likely to ask for increased pay than are men, on average.
The same people who hold up the “wage gap” as an example of systemic misogyny point to underrepresentation of certain groups in certain sectors of society as further evidence that we are evil. Google engineers are mostly men. This must be because Google hates women. African-Americans are underrepresented at elite undergraduate universities.* White supremacy. We don’t even question the inference, because we don’t understand the difference between inequality and injustice.
And yet, when other inequalities crop up that don’t fit the narrative of the oppressive patriarchy, we ignore them. Far more men than women are incarcerated. Women now earn a majority of academic degrees. The NBA is disproportionately African-American. Does the justice system discriminate against men? Do universities favor women? Is the NBA racist against white people? No, no, and no.
If your goal is really equality, then you should be just as concerned about the inequalities in the last paragraph as you are about the “wage gap” and Google’s sex ratio. But the absurdity of casting the examples I just gave as examples of injustice should lead you to instead reject the goal of equality and put justice in its place. Sometimes, outcomes will be unequal, but if these outcomes are the result of just processes, then there’s no reason to worry about them.
*I recognize that, to a significant degree, this is a result of past injustices. Jim Crow, racist housing policies, and the refusal of local governments to protect blacks from racial violence have had an enduring effect on African-Americans, and I believe that justice demands a remedy. My point, though, is that it is these injustices that are relevant to deciding who is owed what, and not the fact that African-Americans are underrepresented in colleges. Even if they were overrepresented, they would be owed something because of the gross injustices perpetrated against them.
