I don't know why, but he brings up a good point...
Is it because you are racist imbeciles?
China is a country of billions run by a federal government that had done a superb job of curtailing corruption in a region historically know for its ever present corruption. One of the primary concerns with the poor state of labour laws in China is that much of the money that is creating the awful working conditions is coming from the US: a problem that many countries have faced over the years.
Admittedly much of China still remains in a rural, poor economic bracket where the law is incredibly hard to administer, but for the most part the government has done a much better job than people give it credit for. I am not saying they don't censor everything out the ass and arrest and kill their own people for "political" reasons, but considering the state of China as recently as sixty years ago you cannot help but respect them. Unless you're a racist know-nothing, of course.
