The point is that replacing the idea of one's worth and potential - girl power/boy power, whatever - with shallow get quick money and get famous schemes is a negative.
Would you prefer children who dream of utilizing their potential to become great at something, like a career path, scientist, scholar, artists, farmer etc., or whose dreams are about becoming Youtube stars or selling crap to a bunch of people?
As for the general remarks on history, power is the only factor in ambition beyond survival. Material success is just one form of power. Fame is power + self gratification for the emotionally weak. Ephemeral fame and get money quick schemes are superficial and weak means to power.
On the other hand, appeals to a universal subject, which doesn't exist, references to human nature, which we can't even define as a term, much less define what the elements of it are, don't really work in a proper argument.
