Meritocracy is still a slur word by the left, that never changed, the left doesn't like meritocracy and the right likes it. So a left winger writing about the horrors of meritocracy doesn't mean that meritocracy is bad.
I find the left/right approach altogether ridiculous for this, it's but a spurious oversimplification which usually shows lack of understanding for the topic discussed. In this particular case, it also shows that you didn't bother to read what meritocracy actually is, since you claim, against the very inventor of the word, that it's a good thing without producing any evidence or reasoning.
