The people who can only read at a 5th grade level are precisely the people who need to be more informed about what's going on
we're talking in the area of 100M+ people, remove accessible reading from them and you're left with what? cable news and tiktok?
I don't believe the literacy rate is a measure of intelligence, when the "three cueing" educational calamity is right there as an obvious explanation. That and Americans just being overworked and exhausted and sick all the time.
