Correction: on foreign producers/competitors who are not subject to the same set of laws, regulations and taxes imposed on our domestic producers/competitors.
I see no reason to extend priveleged access to the "free market" defined by the sovereign jurisdictional boundaries of our Constitution to entities not bound by that Constitution. So long as the federal government imposes restrictions through taxation/regulation on America's ability to fully utilize and enjoy its own resources, tariffs remain the least intrusive form of generating federal revenue.
