I think the supply-chain issue is often forgotten about. Sure, we can open manufacturing businesses here to make whatever, but where do people think the materials will come from? Do they think we’ve had all the materials we need to manufacture goods here in America all along and we just haven’t been because everything is cheaper to make overseas? Just look at this list of major exports by country. Does the US have SOME of this stuff? Sure, but enough to make enough goods for US consumers on a regular, as-needed basis? No way. We will need raw materials, and there won’t be enough to go around.
