I am from London, in the UK.

Pretty much everyone has enough calories (too many in most cases).

As for schools-of course the rich people send their children to much better schools.

Those who can't send their children to local schools. What happens there depends on how bright they are, how hard they work and how committed their parents are to education.

In the case of some ethnic groups there is a strong aversion to educating their girls properly.

None of this has much to do with poverty, emotional closeness or whatever else you claim.
