i think lack of parental support has been around for ages though, which makes it hard to attribute the very recent and sudden drop in reading comprehension, math scores, etc. to it.

ive had to make pretty significant changes to my courses in the past two years. many teachers aren't, or are making changes slowly, which is causing some difficulty.

I would wager up until mid 00s you had one parent staying at home a lot more // work wasn't all encompassing -> which would probably equate to more attention on child rearing although I admit that is speculative. Also means a bit more attention to regulating screen time / inputs etc.
