As China's middle class has expanded, it has in many ways also started to look like America's. In its most recent middle-class analysis, the Pew Research Center in 2016 classified 52% of the US population as middle class. (Methodology for defining the middle class varies, but many experts — including Pew — define the middle class globally as those who live on $10.01 to $20 a day per person, which straddles the poverty line in the US.)
And while the growth of China's middle class is a good thing — those 707 million people have risen out of poverty, after all — some of the similarities it now shares with the US are distinctly less positive.
