So the suppliers abroad will pay more to import those parts (paling in aggregate), but the manufacturer will get a break in corporate taxes and won't be taxed twice when they export their product? Looks like Boeing is going to be selling more jets outside of the US to me.
It could also be argued that trade policy and taxes over the last 20 years created an environment where these foreign suppliers were operating at an enormous competitive advantage by not dealing with the crippling policies that harmed the US counterparts? So now the playing field is being leveled, no?
