>Every elite in history has called itself a "meritocracy". Who defines "merit"?I'd concede that the word itself may have been used questionably to capitalize on the associated ideological goodwill. However, simply stating it may have been abused, does not automatically preclude an actual meritocratic group from existing.
For example, while many generally dishonest individuals (eg sociopaths) may profess to being totally honest, it does not follow that a generally honest person, does not exist.
Similarly, it's quite possible to build something close to a true meritocracy. How do I know? Because this happened at my previous company. Merit, at it's core, was defined by outputs. Nothing more. Was it perfect? No, but we are dealing with messy humans, and subjectivity obviously occurs, but the point is to actively and continually encourage a culture of objectivity.
Over many years the track record bore this out.
There were those that started in 'serfdom' and yet over time, rose up. Actually, not always "up", as in traditional line management sense, but certainly in responsibilities assigned to them. Hence they received associated increases in compensation, benefits and peer respect.
Many know the theory, but how well it works in practice, depends on the ability of those leading, to truly believe and continually act in a way that promotes and entrenches the behavior, so that it becomes the culture.
An example, we had (and they still do), employees on the exec management team that started their professional journey's as junior call center agents. Conversely, those persons that partook in politicized self promotion, tended to enjoy a rather brief tenancy at the company. Either they were actively pushed out by peers and managers, or they passively drifted apart on their own accord, as their natural skills of manipulation and politicking, bore scarce fruits.
In summary, while perhaps uncommon, it is possible to for a meritocracy to flourish given excessive care and thoughtfulness is spent designing fair and useful incentives and metrics. Shallow or ill-conceived incentives and insincere leadership, could set the organization on a ruinous path over the longterm.
