Let me clue you in to a very long history studying import substitution, so many countries that tried it in LatAm failed spectacularly, China succeeded beyond all dreams, the kicker? the big difference? LatAm countries were run by idiots. Trump wanted to build a monitor factory, it flopped and failed as expected he even did the ceremonial dig, Biden wanted a multi billion dollar foundry, no doubt Trump will take credit when it opens soon.
At the end of the day Import substitution high tariff nations ran by idiots only ended up increasing import prices, that is it, cause they are led by morons. You people act as if Donald Trump has savant ideas, no he does not, populism is old as dirt and has been tried before and only really succeeded once in the 20th century and it was by China that did both, import substitution and mass mass export emphasis with a devalued Yuan. Even they are kinda failing with their lithography machine plants.
