Now I'm curious how that kind of thing worked in, like, USSR or how it tends to go in modern China. Like sort of a "to each according to their contribution." Like if merit has a different connotation in a society where people are largely taken care of on a basic level, even if they aren't the "most meritous."
Merit as a way of determining who is qualified for higher positions seems sensible to me in a vacuum, but when we start getting into things like "higher position pays significantly more and has more societal privileges", then it's not just about expertise being placed where it belongs, it's saying that the experts are inherently deserving of more benefits in society. And in a stratified society, what determines who goes on to become an expert can be manipulated through barriers like education and social connections. Kind of like how IQ is a measurement of how someone has been educated, rather than a measurement of inherent "intelligence."
