Recently, I finished two similar books on problems with extreme meritocracy in the United States: The Tyranny of Merit by Harvard philosophy professor Michael Sandel and The Meritocracy Trap by Yale law professor Daniel Markovits. Law schools and entry level legal jobs tend to be intensely meritocratic. The more competitive entry level legal jobs rely very heavily on school rank and student class rank. Once in a private firm, billable hours seem to be the main metric for bonuses and making partner.
Sandel describes at least three problems with meritocracy: (1) people are not competing on an even playing field in the US "meritocracy" (e.g., children of top 1% in income are 77x more likely to attend an Ivy League school than children of bottom 20%); (2) even if there were an even playing field, natural talents that fit community preferences would lead to wild inequality in a pure meritocracy and those natural advantages are not “earned,” (3) a strict meritocracy leads to excessive hubris among the “winners” and shame among the “losers” who believe they deserve their place in society.
Markovits hits a lot of the same notes, but pays more attention to how the elite “exploit themselves”
