Trade policy need to be structured to the overall general benefit of the country economic health (and it's needs vary at any given time depending on its health and problems..its dynamic not static)... trade policy is not to just benefit certain government favored businesses
John Deere certainly wants to be able to export out of this country to other countries so certainly wants us to try and have other countries have open markets.... but John Deere also certainly doesn't want other countries being able to import cheap product that undercuts John Deere into this country.....
and that's only a concern to a business that actually exports or imports in to or from other country
businesses that have exclusively domestic markets ..exclusively domestic manufacturer ... exclusively use domestically produced products ( or any combination of those factors).so are using all or a high percentage domestic labor...are certainly going to be in favor of import tariffs and would care less about others countries reciprocal tariffs on us since they're not exporting anything
that's the whole Balancing Act with tariffs and import export it's finding that Goldilocks zone of not too hot not too cold
but that's the concept of making a deal that's mutually benefits both parties or in this case mutually benefits both countries economies
I only picked John Deere as an example nothing to do with exclusivity. Also you completely forgot to factor in the best deal for John Deere’s customers which is the biggest factor.
