But India - the top on the list is not a poor country and I suspect that the really poor in India are not doing this but the growing middle class are.
This is a bit of a numbers/definition game.
I don't know if there's an official definition of poor but if over half of the population lacks indoor plumbing and makes only a few dollars a day, I'd say most people in the 1st world would call it a poor country.
Many positive things might be said about India, but the notion that it is not a poor country is objectively quite mistaken.
