What you don't understand is that it was America's last generation that sent us to the moon, and China's current generation that will send them to the moon. The brilliant individuals who sent Americans to the moon are all either retired or dead. Their apprentices mostly moved on in 1972 when Nixon killed the program.
I'm sorry, but America's current generation has neither the knowledge nor the ability to design and launch a capsule like the Chinese just did, even if the politicians gave them the money. The "modern" generation has grown up watching MTV, playing video games, and hanging out on the street corners, not building model rockets and studying mathematics and science.
There are no more Wernher von Brauns or Gene Kranzes within NASA.
