If you read more carefully I never wrote that; I was only replying to it. Moreover you're exaggerating the original post. Anyways I'm just providing a different point of view, to which most people on HN are more open to.
> Cry me a river. No one is forcing anyone to come to the US.
Coming from the US middle class to work in another country is different from coming from the middle class in India (or another 3rd world country) to work in the US. They don't have as much economic freedom (or international mobility) as we do.
> Don't like it, simply go home.
That's the problem. Most of them like living here. Some of them don't really have much of choice either given how many family members they have to support. I'm sure there are a lot of companies and managers that treat them well here. Unfortunately I'm also pretty sure that there are a lot of companies and manager that take advantage of them as well (i.e. work extra hours under the table and I'll see about sponsoring you for a green card.) Having a hard time switching companies really sucks.
Given your work experience in both China and Korea, I would be surprised if you didn't experience some of that as well. However, unlike most H1B workers in the US; you probably have better options when you come back home.
