I would be curious what would happen if in order to sell to American workers, you had to meet American environmental and labor conditions. I think that's a total non-starter, but it's a hypothetical that may cause the ponderer to address the huge gap in how competitive other countries are allowed to be to sell to Americans, vs. how Americans aren't really allowed to compete with them.

This plus capital controls would reduce a lot of economic inequality between countries. It would be super, super rough in the short-term but probably globally beneficial in the long term. I believe Bernie Sanders was proposing this back in 2016.
