hierarchy, and will to power. my theory is that looks are markers of everything regarding ,x' person (I.e, it signals whether you're sick or not i.e pallid or yellowish coloration, dark-circle under-eyes, whether you're fertile or not i.e toned skin, rich collagen, healthy weight, and developed secondary sexual characteristics, whether you're trustable or not i.e low-set eyebrows, high-FWHR versus opposites, whether you come from a healthy background or not i.e high-fluctuating asymmetrical faces are due to continuous childhood cortisone e,g trauma, abuse, poverty, your family's history i.e racial characteristics that intertwines with wealthy, intelligence, attractiveness and so on, et cetera). social hierarchies are the natural self-organizing pyramid of auto-reforming establishment by the strong precluding, ostracizing, and massacring the weaker. same reason why leaders are depicted as strong, and, exceptionally smart. the weak living freely without any consequences is essentially a parasitic being, unfortunately.
CEOs are often tall. they're successful without a doubt. It seems you've this idea of an inherent characteristic materializing things instantly, but then you completely forget processes such as how opportunities will land at your front in case of superior genetics. even if someone's smart (which is rewarded due being a superior genetic marker), they'd still need to take actions, and/or rely on others for turning ideas real, as we're, by largely, social animals, ergo why language exists. ex; genius draw a car along ideas of engineering on the side as note, then plenty of low~average-IQ but capable brutes begins the process of constructing the car in real life by carefully, and meticulously following the instructions as formerly dictated. this is interesting because basically most people are useful in some way or another.
