I see no reason why it's inherently unfixable. I feel like there's a bias in our culture that parents will "just know" how to raise children properly. How often do you see classes for teaching parents of toddlers/young kids/preteens/teens how to deal with kids in that age group? There's plenty of resources for newborns, but little past that. Just recrimination and blame for parents who can't get it right. Parenting classes might actually go a long way, but there's no way of knowing for sure right now.
