The American market only wants to buy cheap crap so that is what is made and sent. Usually though the skills involved in making something cut-rate are just as applicable to making something top notch.
American manufacturing skills have atrophied as it has moved to a service economy while as you say the Chinese have been boosting manufacturing for 30 years.
"Chinese" in my ape brain is Harbor Freight junk, or cheap houseware from Amazon with names like "KRLFOCGY".
I mean, it doesn't make sense that typical guidance units for missiles are more expensive than DJI drones. Everyone thinks Chinese products got a little more expensive lately, so they must have quit doing cheap part of cheap and crap, and it's just my gut feeling, but, I would be not so sure about that.
See something like Roomba vs. Xiaomi/Roborock/Deebot/Ecovacs/etc.
This is a real example how western IP stagnates western economy and it's making it not competitive - the IP law makes it easy for incumbents to kill of iteration and competition.
On the other hand, China has major brands in many markets. DJI drones, Anker chargers and cords, Lenovo computers, Polestar cars. TCL TVs and Haier appliances (which I believe also owns the GE consumer brand) are also very common. Roborock vacuums seem to be considered a better value than Roomba now.
It's an interesting counterpoint to the old cliche about paying for brands. Clearly buying on price alone is foolish, as is not considering the reputation of the maker of a product.
