I can tell you from first hand day job experience:
Electronic manufacturing in the US definitely exists. It also is low quality and 5x to 10x the cost of China.
An assembled board that costed us $825/unit in the US (and frequently had errors) costs $130/unit from China and they nailed it every time (probably because they machine QC rather than human QC). It's really not even close. Same goes for machined parts - drastically cheaper and higher quality from China.
