I don’t think political correctness is the correct description of what he is trying to complain about.
The word he is looking for is “entitlement caused by excessive privilege.”
The reason people in China work that hard is that there are many people in poverty who would also like to work very hard for those jobs and very little safety net.
I should also mention once again: The United States is nowhere near as racist or sexist as these countries as mentioned above.
However the common opinion is that the United States is extremely racist and sexist. To people who genuinely believe this: You have no idea what the rest of the world is like, please travel.
The things I have seen folks from China openly saying and doing in business make the United States look very fair.
