I think most people just buy trash at WalMart and Amazon and it's 99% Chinese disposable junk. That doesn't mean that China is incapable of producing high quality goods, but just that the average interaction that people have with Chinese goods are low quality.
It's the manufacturing equivalent of "How could the government be efficient? Haven't you ever been to the DMV?" (set aside that fact that many DMVs seem to be quite efficient these days)
