How many jobs would remain in the US if there would not be that cost difference?
Well, for whatever I bring from China, I would never produce it at the domestic cost. Andy while they do it using manual labor in China, It could be done by automation, but I don't know if that's used for small runs like mine.
If it could be produced competitively in the US due to automation, There are probably 4-5 human jobs involved in the production, even if nothing involved manual labor.
