Exactly. The monkey's paw didn't even hold up its end of the bargain with a tainted promise. Covid killed millions, is still killing at a rate that isn't even permitted to be tracked while causing repeated incidence of brain damage with increasing severity, and yet we're still poisoned by microplastics (along with vast swathes of the rest of the biosphere) which is likewise a serious and worsening issue that isn't getting covered much for similar reasons that Covid is ignored and denied.
On top of that, I'd bet my life that PFAS ("forever chemicals") are doing more harm in more places than almost anyone realizes yet. So far as "leaded paint of our time" goes, the difference now is that instead of pretending to give a shit and make at least some inadequate efforts to correct or regulate the issue, the response ranges from "yeah, there's all kinds of nasty shit out there like lead but that's just how things are," to "lead isn't actually all that bad" to "there isn't lead in the paint, that's a hoax so there's nothing we need to do." Hell, they won't do anything about lead in the water now so long as it's only poisoning the poors. Shit is bleak.
Given that you recognize there are multiple factors that are going into declining education and student performance, deep systemic problems that long predate 2020, what makes you think you have enough information to blame any of it on lockdowns?
Lockdowns didn't last for years.
I had this exact problem with students (it was a widely discussed phenomenon) many years before Covid. I knew instructors frequently complaining about it even in the 00's.
I don't usually care when someone doesn't know what a word means and uses it instead of the correct word, and even if I did I wouldn't normally point it out. I'm sure I make errors like that at times too. But given the context here, I think it's relevant and fair of me to do so. "Exasperated?" Really? Anyway, you say it's not "exclusively" a lockdown problem, implying that lockdowns were still a major cause of the problem. But what evidence do you have that they contributed to it at all beyond a vibes-based opinion?
I'm not trying to be overly harsh with this response, but it really bothers me that people are blaming these long-standing, well-known issues on lockdowns when not only were lockdowns not the problem, but had they been longer (and better implemented in general) they could have actually saved millions of children from the cognitive decline they are now and will continue to experience as a result of a pandemic that literally gives them brain damage.
