People in China will buy their own goods just like we did prior to globalization. They have 1.3 billon potential buyers. Then there is Russia & India.
The true wealth of a nation comes from using inexpensive natural resources and energy. Those 2 things are what drove the US economy until the 60’s when buracracy started to really get in the way. When those go away and all you have is paper shufflers then it’s all monopoly money because there is no true value or commodity.
China & Russia have vast untapped resources with no regulatory busy bodies to drive the costs up. It is almost like free money, dig it up and sell it.
