This reminded of the YouTube guy of "Smarter Every Day" who tried to manufacture a a grill brush completely in USA and still be competitive in the marketplace (i.e. China) [0].
It turned out that USA / "the west" lost the engineering knowledge to manufacture "stuff" (in this case injection molding and other procedures): Nowadays, we simply create the plans and schematics (e.g. CAD files) and let the Chinese do the building.
