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.

India is not Sub Saharan Africa poor but has ~20% of their population living in poverty which they define as something like 50 cents a day.

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.

Wow, bold claim. India's GDP per capita for 2017 is $7,200, ranked 156th in the world. I'd say they're not far away from being poor. Source: https://www.cia.gov/library/publications/the-world-factbook/...

By poorer I mean less income counted in GDP. The lower cost of living make it more viable for parents spend more time with children. I could also argue India is rich compared to, say, Japan, who don’t have much resources to spend on having children.

It's 156 in the world by GDP per capita PPP (purchase power parity) with under USD 8000 (USD 2200 nominal), so cost of living is taken into account, and a HDI of 0.624 (131st in the world).

Many positive things might be said about India, but the notion that it is not a poor country is objectively quite mistaken.
