The post documents issues like some assembly workers stuffing so much wire into the post that not enough protruded to make a connection. I will hope that in the US the workers are paid enough that they notice/care that the result can be connected. Or the managers.
Do you want documented experiences of Chinese manufacturing repeatedly attempting to cut corners? Like substituting inferior goods to increase their profit margin even after the initial product line is running smoothly.
For this not to be a problem a worker would have to notice it and put two and two together, then investigate further and then persuade their supervisor to raise it with the customer and get a change made to the spec.
While enjoying your faith in the rigour and attention to detail of the US assembly line worker, I think this example tells exactly the story the article says it does - that you have to specify everything.
He tried to source from America companies first, but the products were actually worse and much more expensive than his Chinese vendors.
He has one blog post which details the quality differences, and the Chinese vendors were much better than the American ones. The American ones also took longer and we're less communicative to him than the Chinese vendors.
