Ok - so you add some jobs but the profit base is not here, it's in the home country. And politically speaking, after you deploy the tariff why would you think a Taiwan or Korea would give the green light to take jobs out of their country and move them to the US? If you impose a tariff and start a trade war why would Seoul agree to lose a factory there to build in say Tennessee simply to sell a few more TVs?
I see where you are going but it's not that simple. Honda/Nissan/BMW for example are here because they were getting killed on the foreign exchange translation of shipping into here. Now they can do everything in USD base and keep it here if it make sense.......but, they can also take the profit home if the USD makes it right.
But to have a foreign company build here post a tariff I think is near impossible - both economically and politically.
The other side, of course, is that you also make it profitable for those manufactuers who are here to expand and for new American startups to fill the marketplace.
We are the best market in the world. Daewoo will come. And especially if they see their market share being overtaken by homegrown expansion and startups.
