Scale is a force of nature of human advancement.
We can see geography invariance, viz. WeChat, TikTok existing in China where facebook, twitter are not allowed to exist. If these didn't exist, something else would.
Scale might have begun with printed books. One author writes something, that is printed as many times as the market demands it. She does not have to lift her pen again. And with her grand success, other authors have to find jobs being private tutors of children of barons and dukes and such or finding adjuct roles in community colleges in modern times. Hell, there is even competition with dead people in this trade.
But accountants, devs, barbers don't have to face this.
And, I am not supporting this. I know that these girls should not have to face this. But eliminating social media is not the answer, but having better interests is. (This reeks of snobbery and privilege, I know.)
Almost all teenager girls I know or knew, did not feel this way for social media. Because they have/had better things to do in life. They were busy with ballet, prep school, volunteering, math clubs, music class, etc. So, there is also a socio-economic aspect to it.
As a heterosexual male, I never conformed with the mainstream beauty standards. I, and hence my potential and past partners did not have to face the bad side of scale.
I also actively, regularly listen to young pianists on Twitch and donate to them, rather than some decades old recordings (better, too) I could find for free on YouTube or Spotify.
I see it this way- scale is inevitable, and even desirable (one girl makes 3000 girls jealous instead of 30; one Physics teacher teaches 300 girls instead of 30- who otherwise would not have access to one- scale is not evil in itself), but you can bypass its effects if you properly want.
