How about the quality of the education and curriculum itself?
The curriculum can be amazing, but it doesn't matter if the students don't care. And frankly, a lot of them don't. Some of that is cultural, some of that is due to parenting. A lot of parents aren't involved in their kids education. Frankly, a lot of them are barely involved in parenting in general.
Now, if someone came with a headline that said "Parents not involved in childrens education because they've been ragebaited into spending all their time yelling on social media" my biases would tend to lend me to believe it's true, even without sufficient evidence. There are other correlations, like cellphone ownership in the population.
Just having social media itself doesn't seem to be an exact fit, but that tells us nothing about the algorithms that social media was using at the time.
