Tangentially related, the Daniel Suarez sequel novel, Freedom(TM) presents a similar scenario. People will have a rating system based on their interactions with others (think eBay) and you can see that rating. Four stars out of a base of 81 interactions - from the postman to your boss. I have a hunch that China's generally compliant, anti-antagonistic society, makes the Chinese system easier to implement. In a western country, I think it would turn south really, really quickly and for much worse.
