This is an admirable thing. But as China develops and grows - conditions becoming more equal between the US and China - it's only natural that Chinese expats will find that they can seek "riches" in what they feel is their homeland.
There's nothing wrong with this, and in fact will be good for people of all nationalities as competition increases for talent.
I can see your argument about returning to an "original homeland" (i.e. for reasons of cultural or social affinity), but "natural homeland"? There's nothing about the nature (air, land, climate, flora, fauna, etc) of China that is uniquely suited to a Chinese person any more than anyone else.
