Chinese companies learn from the best (us). And they are only responding to demand. The blame for low-quality goods cannot be placed on China. The blame is squarely back here at home because low-quality, cheap goods are exactly what the American market is demanding, and demanding big time (Temu and Shein are wildly popular). No one wants high quality goods at higher cost. We all say we do, but in reality we don't, and our buying habits just reinforce that. No you can't blame China, sorry. The destruction of American industry is entirely a problem of our own system. American companies deliberately destroyed American manufacturing (and employment) in the name of short-term, quarterly profit. China didn't cheat and steal our jobs: we gave it all to them on purpose. No amount of tariffs and taxes will change that.
And for the record, I've had to deal with poor quality goods made in the US as well. Cutting corners to save pennies applies just as much to American manufacturers (maybe even more so) as it does to Chinese manufacturers. For example, Eaton Cutler-Hammer electrical panels are the most flimsy things I've ever dealt with. Every possible cost was cut.
