Do you think any parents who live in a big city will want to move to village in order to raise their kid? I don't think so, money is more important then child for them, so if they move to village, they can't work in big city again. It's make sense since bad financial is worse than kid grow without his parents.
Bad kids can be raised anywhere, either in the village or in the city as long as they don't get the good parenting they need. A child can be given out to a village and end up being abused and grow up with that mentality, get the wrong impression of people around them and use that sense to communicate with people and the same goes for the city too. However, I think the guy is trying to give priority to society's notion that children that are raised in the village usually come out to be properly raised well when compared to city boys.
At least they still can hire an assistant or babysitter in order to teach and raise their kids.
I don't know if I am the only one who doesnt like a babysitter the way the world now operates, no matter what the parents do, they should always find ways to make time for the child/children, it stronger the bonds and makes the kids adhere to their ways easily.
