That goes on up the chain, though. The reason manufacturing left the U.S. was because it was no longer cost-effective to pay American wages at the prices prevalent in consumer goods industries. Had we kept manufacturing on-shore, the price of goods would've mimicked services like health care, law, and education, all of which have undergone very significant inflation, much more than the economy-wide average.
The result of this on-shoring craze (modulo automation) is that we're likely to see very significant inflation, basically taking us back to the cost structures we saw in the 1980s. No more cheap Chinese or Vietnamese goods at Amazon or Walmart; if we have to Buy American, expect to pay the differential between Vietnamese and American wages, roughly a 30-40x increase.
