Your comment adds nothing of worth to the discussion. So what if you don't see any problems with meritocracy? Explain why you feel that way.
A fundamental assumption of the article is that every person is of equal worth. Anyone who objects to this idea is labelled as racist or sexist or whatever-ist. But it is objectively just not true that people are all the same. A murderer is not equal to a doctor. Most people would choose to save a drowning doctor rather than a drowning murderer if forced to pick one. Similarly, if I a rational person had to choose between saving a drowning doctor who is an idiot or saving a drowning doctor who is a geniue, the rational person would save the smarter doctor.
