Its very easy to judge China through a western perspective; you just say "it was judged through a western perspective." Judging is always relative to a perspective and is useful to evaluate your situation. The author's article is not meant for Chinese, perhaps, but for other foreigners, and therefore its useful and not "bitterly biased."
Foreigner laws in China are designed to protect us? Ya, by not letting our kids go to any but the most expensive international schools? By making us re-register with our local PSB whenever we go on a business trip? By limiting how we can spend our money..which we earned in China and paid (high) Chinese taxes on? By making us pay social security taxes and then telling us we will only see that money at all if we work here for 15 years?
Why do Chinese always take criticism on China so personally as a face problem? Its common western practice to criticize something that you don't think is working right, we just treat China as an equal topic in that regard. Its not an attack, its just commentary.
