Folks have been predicting collapse of China for like past 30years , so take it with grain of salt. Besides wide sweeping exemptions (nearly half of Chinese imports) on tariffs. So it will not all just collapse , besides chinese will dodge much of it with near shoring stuff to bypas tarrifs and ultimately Trump will blink before the Chinese , not because of China but his moneyed pals applying pressure.
Note Chinese have built up global market for their product. US market makes up for some 16% of their exports compare that to 20+y ago when it was like 48% of Chinese exports , 16% (sub 10% if you count exceptions) doesn't sound like an exorbitant leverage. Besides if you google previous Trump tradewar with China ,the results were a wash paid by US consumer . Besides when it comes to trade wars there is always some lag between manufacturers and consumers feeling it. Give it a month or two .
