Some countries restrict US imports and/or make it difficult to do business there in addition to tariffs, while they freely export to the U.S. That’s the unbalance.
Yes, making more stuff in the U.S. may raise prices but some of the cost savings from cheap foreign production just goes to extra profits not increased prices. But yes there is some trade off with higher prices for some things but the up side is more jobs and more products to export. Once one company outsources cheap labor then they all have to do it to stay competitive and stay profitable.
Perhaps more importantly it makes us more self sufficient. Being too dependent on foreign products is a huge problem as we saw during Covid. Nobody including the imports have a problem building cars here and selling them profitably.
