Great point about agriculture. Fortunately, telecommuting enabled me to stay on the farm, which couldn't support me by itself. Had I been born a decade earlier, moving away to a populous area would have been an almost certainty. If you have to move away from your family, the risk is already high, so what's a little more? Now, the vast majority of the population already live in urban areas, so we are back to not having to move very far from your family.
I didn't say much about it, but part of what I was thinking about is that someone who has had the experience of picking from many choices is probably going to give better advice to a child doing the same thing than someone who had one path that was quite clear.
(Which isn't contrary to anything you said, it's just another factor)
