It is kind of a brute force methodology, but it is kind of all we have. We would need a more elegant understanding of the problem space in order to address such things effectively without relying on some kind of racism/classism/OtherIsm to select for who needs some help getting a leg up when they are routinely left out by our current processes. Perhaps we can gain that understanding, but if it already existed, we wouldn't have the problems we currently have. So perhaps not a good time to hold out for some perfect solution.
