Yeah - meritocracy sounds great in principle. And, we can agree that it's leagues better than aristocracy. But, over generational scales, aristocracy and meritocracy are very closely aligned.
Meritocracy begins first with a wave of smart, risk-taking, hard-working, uncompromising, (perhaps immoral) people who usurp the establishment. And, we certainly celebrate that. It brings a shift, and usually rewards many others.
But, it's when those same people put their children and grandchildren in positions where risks nearly vanish that we worry about. They naturally give their descendents their connections, secret knowledge, wealth, safety and other benefits. And, they unconsciously change the rules to favor themselves. And, they seem to dismiss all those elements when their spawns happen to reach similar heights. And, slowly, they begin to believe that it's some genetic component, or something innate in them, that has caused it. And, then the new aristocracy is born.
I think the article is bringing attention to this, and it's good to do so. The new rich should be allowed to let their children and grandchildren live great lives. But, those descendents should not become the gatekeepers of the rest of the world's amazing talent. There are just to many brilliant, hard-working people in the world, who aren't connected, who need a chance.
