Even to the (insufficient, overblown) extent that it happens, lifting “the poor” Han Chinese out of poverty by putting other populations (Uighurs) under slave labour instead, is not the moral win you’re implying.
If an ethnic cleansing is part of the requirements, to stop committing humanitarian atrocities towards “the poor”, that’s still an atrocity.
Disclaimer, the USA, just like every authoritarian state, is also disgusting and criminal.
