Not quite sure "Ow My Balls / Jackass" argument should count, the Jackass franchise is older than Idiocracy and was most likely an inspiration for that bit.
And I’m reminded of The Dark Knight Returns (1986) graphic novel. There are grotesque parodies of talking head news anchors and even a caricature of then-president Ronald Regan. Situation all fracked up.
Reality TV shows are a HUGE HUGE HUGE segment; most of them aren't too far off. (Reality TV as a concept precedes Idiocracy but was refined in the 2010s.)
"Ow! My Balls" was less about the Jackass part of it but more about the "numbing your brain and consuming mindless entertainment" commentary. Reality TV fits this category extremely well. See also: Housewives of _x_.
Brawndo is considered a match with "Nestlé CEO says water isn't a human right". Beyond that it has nothing to do with agricultural malpractice, the Nestlé guy is just correct. It doesn't make sense to talk about human rights that way.
"Ow my balls" is considered a match because "YouTube's most popular content is often people hurting themselves", which is just wrong. It's stuff like music videos, children's songs and MrBeast. All quite wholesome.
"Costco law degree" is considered a match because ... there are companies that offer credentials which aren't universities. That isn't evidence of stupidity.
"Trash piles are massive" is considered a match because third world countries have giant trash piles. But they always did. Idiocracy was a film about America.
Even the first match is a giant stretch. Elizondo was only a TV star, and he did that work whilst in office. Trump wasn't (just) a reality TV star, he was first and foremost pre-politics a real estate developer. Quite different levels of challenge and respectability. And I don't think the show he did could be described as reality TV anyway.
