There has historically been a lot of US-critical content manufactured by the US, which normally deflects criticism towards individual failings, external enemies, or surrogate political effigies. A few examples: Falling Down, Bulworth, American Beauty, all the other 90s/00s media critical of suburbia, 24, The Daily Show. Most of these are left-coded, I’m not as familiar with the right-coded stuff (I usually tuned it out) but from what I can tell it’s usually aimed against foreigners and weak/effiminate liberals. 2010s/20s race activism made “white people” into the effigy for the first time, but that’s still a deflection.
Pre-sale TikTok was the first time that a mirror was held up to US politics from a global perspective, where the masses could get a less fitered and channeled understanding of how they are seen by the world. (Reddit provided this previously but it has fewer users and less impact.)
As much as I hate TikTok and short videos, it had a big impact. There’s a reason that they forced the sale. Domestic control of mass media consumption is the primary method by which public opinion is shaped within the US.
