From Clifton Mark, in Aeon:
Despite the moral assurance and personal flattery that meritocracy offers to the successful, it ought to be abandoned both as a belief about how the world works and as a general social ideal. It’s false, and believing in it encourages selfishness, discrimination and indifference to the plight of the unfortunate.
As with any ideology, part of its draw is that it justifies the status quo, explaining why people belong where they happen to be in the social order. It is a well-established psychological principle that people prefer to believe that the world is just.
