Is a poor person in China today better off than a poor person in the US?

Suppose we define poor as relative to the median i,e consider say the bottom 10% of the US and China in terms of income. I have heard the argument that even if the American might make more money then the Chinese person, the Chinese person has a better quality of life.

One of the mains reasons I was given was healthcare. How true is this statement? I am not from either of these countries so I wouldn't know how you compare them.
