I've met contractors who did extensive work for businessmen in the US, who then turned around and told the contractor, "You want to be paid? Sue me!"
The whole culture of trust / fairness / honesty is very different from the west.
Is it really that different? There are some people who are good and some people who end up being opportunistic in evil ways. The more I learn about differences across cultures, the more I conclude that the differences are always ones of degree, and the differences are made more visible due to the cultural contrasts. That said, is there more rule of law and enforcement around IP issues in the west than in China? I suspect that's also true.
Dealt with our products being knocked off for years, wouldn’t want to buy cancer meds ever!
There are also people in the west who aren't above faking treatments for cancer.
