I'm not sure how you can compare the US, which does have it's problems, but is one of the least racist (and offers many more opportunities to people that start with nothing) countries in the world to China, one of the most corrupt and authoritarian.

If people actually cared, they would look at the gross human rights abuses by the Chinese government.
You just don't see things like this:
