China's middle class is already larger than the entire US population, and growing fast. It won't be rich in the sense that say Switzerland or Norway are rich. But it seems safe to say they won't be barely scraping by.

IMO, India likely won't make this transition. It's population is still growing but it's birth rate is sinking fast (like most everywhere else).

And China's lower class is nearly double the size of the US population, making a median of $150 per month.

India's demographics don't look as bad as China's, so I'm not sure why you're less optimistic about them.
