As others have pointed out in responding to you, you don't only have to be following the super-rich and super-successful for your feeds to project an image skewed toward their experiences.

Thanks to the heavy-tailed distribution of most aspirational resources (whether that is followers/friends, likes/retweets or various offline resources), we encounter a "generalized friendship paradox" (see https://doi.org/10.15195/v1.a10 among others) where on average our friends in our social networks score more highly on a variety of attributes than we do.

So it's enough for us to follow a few individuals on the long tail of a distribution for the paradox to apply that, even though most of our friends might not be particularly impressive individuals when compared to ourselves, on average our friends are much more popular, successful and beautiful than we are. Thanks to the structure of our networks (and online networks might have greater skew than offline networks), socially-induced anxiety can come about quite quickly. Not a lot of curation is needed.
