I agree with you, it takes a small friendly village (or at least a largeish multigenerational close family nearby at the lowest minimum).
But we are in western 21st century, people leave their places of birth for myriad of reasons, some better than others but all equally good for them, given its almost never easy to lose one's roots and just move on one's own.
I am in this category, we have 2 small kids and any family is at least 1000km away, the actually helpful good one more like 1500km (and no its not just a hop on some local planes, rather full day ordeal at minimum). No nanny. We see how kids and grandparents enjoy each other, grandparents have more... mental capacity? to teach them after our long day at work and so on.
But there are reasons we moved, its complex mix of leaving poor corrupted place with higher criminality where kids would struggle to achieve a good life via moral legal work and just good efforts. Not everybody has the luxury to come from background where the only difference is amount of money earned. So you give kids a better start and environment, while giving them much smaller set of role models and people who have time for them outside school.
At the end its our choices and our responsibility to raise them. No phones for a loooong time, and even after that some dumb nokia. They can screw up their lives on their own once adults, we won't contribute there even if it would be tremendously easier lifestyle.
