Yes but the USA has a PPP GDP PC of 76400 G–K$ and China has 21500 G–K$. How can you in good faith compare those?

(Life expectancy for Mexico, marginally richer per capita than China is 70. Life expectancy for the Philippines (poorer pc than China) is 69.)

The fact that China is in the same ballpark should be evidence enough that their policies are more people-orientated. The fact that they're ahead despite the huge disadvantage should be a huge point of shame for the USA, not something to be dismissed with saying the gap is small.
