This rot is also existential, because as domestic players die, that knowledge is also lost.
American-made goods have the worst cost:quality ratio for multiple reasons. Capitalism hollowing out quality, businesses capturing markets. They sit in an area which are unaffordable for your average American as a result of the middle class vanishing and not boutique enough for the wealthier ones.
People voted for a wealthy man to loot everything and he's doing exactly that.
This is even more pronounced because these are the people with cash who spend it. Billionaires aren't bingeing Amazon, shien and temu. That 60-90% class of Americans are the backbone of the economy. And they buy tons, tons, and more tons of Made in China.
The one percentage have a staggering amount of wealth, but it's mostly in assets.
The "upper/upper middle class" have just as much, but it's much more heavily in cash. Those people and their spending is what keeps the economy moving. ~70% of GDP comes from them.
You should check the actual wealth distribution rather than just reading incessant "The 1%..." headlines.
