We don't need to pass a law to bring manufacturing supply chains back to America. We just need to enforce the law already on the books.
The Trade Act of 1930 is the law. This landmark trade legislation has clear enforceable labor standards. It bans the importation into the United States of any goods made with slave labor or child labor. The Obama administration, to its credit, closed a loophole in the original act to make it a powerful weapon for protecting American workers and American labor standards.
