China is a split society. Many are still in poverty, per capita gdp is very low. However it’s a huge country and several hundred million now have western standard of living.
This is definitely true, although it is worth noting that many of those in rural poverty have also seen huge improvements to their condition (number making under $2 PPP/hr has gone from 700 million to 2 million in a matter of 2 decades) and many of the cities in traditionally rural provinces are booming.
