No such thing as a free lunch. Even if China and US were friendly states, there must be a solid reason why/how China would benefit from developing "the infrastructure and industry" in US, and the level of benefit must outweight the cost of transferring money to them.You missed a keyword. “Transfer.” This author is not asking you to invest into them. He want China to send the US gov free money as compensation for them buying Chinese products.
The author firstly assumes we live in a world where countries are all friends that sing kumbaya together while holding hands and developing eachother. Reality couldn't be further from it. For example, under the Bancor system, Israel would have to transfer money to Lebanon. Because the people in these 2 nations greatly hate eachother, it will be impossible to find a common ground of mutual benefits that's acceptable to both.
The second egregious assumption is that forming what amounts to an international Kholkoz would be an anywhere near effective use of the resources for the more advanced nations.
Maybe to a high schooler, it sounds smart that "duh the rich and industrialized help the other get up on their feet and everyone prospers more because everyone is happy!!!". This is some CHAZ level idea.
Edit: a man named "Philip Pilkington" in my mind doesn't exactly project the image of a cocomelon watcher. But names can be deceiving. Maybe he is a teen. Or at least mentally one.
