The people who have the most power are the ones who have the most reason to like meritocracies and keep them in place. It’s system justification. We may think that meritocracy makes no sense. But on the other hand, if you have a brain tumor, you’ll want to make sure you’re operated on by a great doctor, not some random person off the street. You need to make sure that competent people are doing the difficult jobs, without telling them that they’re better humans as a result of that, and without having them think that in any way they earned that. The problem with this idea is that it can kill motivation.
