I agree with @OddRails, in that I don't expect manufacturers to suddenly start investing big money in new production facilities. It would be a huge investment, and who knows how long the tariffs might remain in place? We live in a world market in these days and have to recognize that we can't be the sole producer and exporter of goods and services. So as one person stated, I think this is maybe just a huge tax increase on the very people he swore to reduce taxes for. The only positive I see is maybe it will help lower deficits and the national debt, but the negative effect on the economy may offset that as well. One other benefit may be if other countries lower their tariffs on US goods, but they seem to be moving in the opposite direction at this point. I think Mr. Trump wants to use these tariffs as negotiating points, so it remains to be seen what gets negotiated out of all this.
