The reason why youth is preferentially valued is that wisdom is not: the youth work within existing systems and frameworks with agility and without questioning them, they don't yet have the experience to deeply challenge those frameworks. It's not that there are no older people at companies, it's that there are few at the top, who don't want to be challenged. They want people who will efficiently follow orders. The best kind of person to follow orders is one who doesn't even know how to begin questioning them yet because he simply does not have enough experience yet. Ironically then, the preference for youth exists in order to prop up old paradigms. This is a cultural artifact of the current era not some timeless principle.
