I think you are misunderstanding, China pays for 10 cities and gets 3. No one denies the immense infrastructure they have. People deny that they did it practically, which they did not. If the US wanted to match Chinas debt level (national and provincial), they could burn $30 trillion for $10 trillion of eye popping functionality too.

Also in the US, private markets primarily fund advancement, not the government. Private markets generally don't burn money like governments.
