After starting a business in China I spent a year in London then a year in LA. What irritated me about doing business in the US was the pain of complex inter-state tax nexuses, dealing with government in general (TSA etc.), immigration and expensive legal overheads in general, the need to drive everywhere and the long distances to get to the rest of the world. Certain things, such as the lack of a global perspective in most of the locals, the cheapskate approach to employee holidays, and a half-broken financial system were very similar to China.
