Fun fact: When Maslow set out to study self-actualizing people, he wasn't interested in "high achievers" or "high performers" or those who were "crushing it". His impetus for studying self-actualizing people was to discover the characteristics of a "good human being".

In terms of worshipping high achievers/producers - maybe the original roots of psychology & statistics in eugenics, i.e., IQ testing, as well as the power of capitalism, simply are too strong to be overtaken by relatively new perspectives on self-actualization & personal growth.
There's also real pragmatism in additional to cultural momentum. A temple of enlightened monks beating off invaders with guns (or weaponized economics) only happens in movies.
