I have friends and family who are Chinese. Although it is not a universal ttuth, the fact is that many Chinese see the west only as something to be exploited, and do not wish to play by the same rules. This applies to individuals who have come here to work, not just the government or Chinese businessmen. The sentiment is that China was exploited inygr past, and now it is time for payback. One deals with China and Chinese without this backgroud at one's peril.
There is some of that, but it isn't "getting back." Its like going to Italy and getting ripped off as a tourist; there are plenty of people looking around for an opportunity for a quick buck on the gullible, Foreigner or Chinese. Then couple that with poor rule of law that make scams and unfair exploitation feasible, and you have China (as opposed to say Singapore, which is mostly Chinese but rule of law is strong and people are less hungry for a quick buck).
