Demand less government regulation and you end up with John D Rockefeller and Leland Stanford, ethics. COSTCO and WalMart have no freakin' way in the world to verify origin nor anything else but weight. Railroad train cars of made in Mexico plates and sub assemblies never mind batteries can roll into Johnson Controls or US battery and under NAFTA they do not have to declare it if they glue the lid onto the battery. Get the picture.
Wanna hear silence? Get on the blower and ask these companies: Is any component of your XXXXX batteries not manufactured in the USA? If so what is the percentage of the accumulator made or assembled outside the USA ?
