I think there is some truth in that there is some amount of "social construct" aspect, rather than being intentionally conditioned, that is a form of the "mimetic desire" Thiel always talks about, where you subconsciously want what others want. But where I disagree is that "skinny women big breasts" is an outdated archetype, from about the 80s to mid aughts (2000-2010). There's still the same mimetic desire on beauty that wades into unhealthy territory. "Curvy" is actually quite en vogue and on the extremes, there are many women getting elective plastic surgeries and injections on their lips, butts, and elsewhere, much moreso than the previous archetype. That used to be quite taboo, nowadays it's much less so. And as sure as the sun sets, there will still be ever changing shifts in mimetic desire of beauty among the next generations, just as older men still might favor the "skinny big breasts" archetype today.
