they are both correct.... at first, prices WILL BE HIGHER, due to tariffs and the inability to buy what they need here in the USA so the tariffs will make things pricey for all of us,
but, if businesses are brought back here and the new manufacturing plants built here are built with the newest artificial intelligence technology, then the savings of A/I robots will be cheaper than labor and all the costs of labor like benefits and taxes that they would have had to pay.
What you are missing is this is not a Bewitched situation and just a wiggling of ones nose, makes it appear.
It will take some years of transition that will cost us heavily, upfront..... but in the end, if corporations decide to pass their savings on robots on to us, prices will eventually go down....is my best guess.
