Agree. There are so many issues Xi is facing. The bottom line is about resources. With a large population moving towards an older society, China needs young manpower on one hand. On the other hand, more people means consuming more if China encourages immigrants in the case current young generations do not want to raise more children. China should abandon the idea of 高速发展。I am a person worrying about building up too many high speed train rails. Most businesses do not need that speed if high speed trains are mostly running with debt.
