Probably still the lead as a major contributor. The phaseout started when elder millennials were young (iirc the timing right). Its still pretty prevalent (Portland schools system as an example) in a wide range of places. And for anyone young enough that has managed to avoid it, they were likely raised by someone who was affected by it so its a learned behavior passed on kinda thing.
Yeah, social shittiness that has been passed on from generation to generation over time. Lead and other pollution might make it worse, but the vast majority seems to have a social basis.
