I mean, we already have YouTube channels and tiktok content that are about the same as the TV show "ass" shown in the movie.
Although to be fair,some of that happened before Idiocracy came out.
With the public money used for sports stadiums, that element of the movie to have government sports teams is slowly coming true also.
Further, colleges receive public money but are not free to attend for most students. And I am not talking about "free" from the students perspective, I mean most would not be permitted to enroll if significant tuition dollars were not deposited (unlike public schools, for instance). Also, plenty of colleges are private but have NCAA teams.
