I'm kinda 50/50 on that. Parents should be doing better, but most are probably unequipped to fight A.I., short-form video, social media, and other things that harm focus and education. You also cannot just expect parents to do better and hope that they will change. Parenting is not subject to very much government regulation (for obvious practical and ethical reasons) but education systems are, and can be changed systematically through law or policy.

So I agree that parents are responsible, but there's not really any kind of systematic change that I can imagine would fix that problem.

I agree but also would say they're powerless to fix it if they want to. Everyone is on the hamster wheel, zero support from government and society for dual income families, run between work and childcare/school, after school activities, caring for aging parents. If you're a single income family perhaps you trade better parental engagement for the crushing weight of financial woes. Parents are stuck doing the bare minimum and just surviving, not thriving.
