I'm not convinced by the genetic IQ argument. If there is a genuine difference, and measuring, even defining, IQ is not as simple as height or weight; then I suspect it's more likely due to teaching methods, or just the amount of effort put in. If China has a real advantage I'd suggest its the number of engineers involved at senior levels, people who have been trained to make things work as opposed to make things sound like they'll work. It also helps that they can do so without having to worry unduly about getting elected, although I'll bet the internal politics of promotion within the party hierarchy makes Westminster and Washington look like playschool. Nor do they have to be particularly nice to the common people who stand in their way.
