"Capability is substantially more genetic than environmental anyway"
I am confused how the Chinese can have such a surging middle class if it is genetic. Certainly they have not changed their genetics too much in the last 50 years.

A large middle class is pretty much exactly what you'd expect based on the testing.
Why would anything need to have changed in the last 50 years?
Are you talking about the Great Leap Forward, which killed tens of millions?
You realize we're discussing individuals getting hired in a job market, not genocidal dictatorships in Asia 50+ years ago, right?
