You keep repeating the same drivel over and over again without realising what it means.
The complete loss of the US market of 400 billion means 3% of GDP. This is hardly several points off its GDP. But this won’t happen as America can’t do without Chinese products. Watch some videos about the recent Canton Fair and you will see how China is doing with the rest of the world.
With regards to purchasing power, you don’t seem to understand the concept of relativity. Chinese citizens don’t have to pay sky high exorbitant public services costs like healthcare, transportation, insurances etc. I can’t say for sure but I’m willing to bet that someone earning 13,000 in China probably has a better standard of living than someone earning 89,000 in the US. PPP in China is way ahead of America.
@NoDisplayName has suggested an alternative reason for the destruction of many apartments which I find more credible than your propagandised claim.
As for the population demographics, this may or may not be an issue but even if it is, it will only surface many years from now by which time many things would have been automated eliminating the need for much labour.
As for Asian nations being terrified, that’s more in your head than in reality.
America can’t win this trade war. China is the top trading nation for over 140 countries. There is no way these countries will cut off trade with China to support, as a Japanese politician put it, a delinquent kids’ extortion demands. The Japanese delegation has returned home with no deal. The US just doesn’t have the cards they thought they did. The only area in which they currently reign supreme are in chips but you can be sure that this is slowly but surely being eroded away. All its actions have clearly shown that they are “terrified” of China. Why? Because they are losing!
