Everytime I hear a vitriolic rant against Chinese these days I see the that disclaimer. Sometimes it even comes with the "I even have some friends..." cliché.
But on the face of it it doesn't make much sense, many of the things you are ranting about are problems within the Chinese society where the government is actually much more forward thinking than much of its people.
For example, quality control neglect and corruption and fraud are very common elements to Chinese society, and their government recognizes the damage that these criminals do to the country's reputation and have cracked down on it. The government is ahead of their corporate culture right now, and a big reason is the pressure that economic contagion provides.
The fact that China is exporting to the US is raising their standards because the US market has higher standards. China is
making progress and will continue to despite the xenophobia that drives this kind of vitriol.
