So one video about a city in China is a reflection of the whole of China?.. You know why the US is more developed than China, because the development in the US is well distributed all over the 50 states whereas in China once you leave the shiny cities to the rural areas and villages is a different picture. And the US GDP remains higher. But I agree China is catching up fast especially in the forgotten areas but still has some years to catch up to the US overall level. Ask Chinese who still escaping and trying to enter the US illegally for a better life.
