Trump has said the issues are currency manipulation and those countries whose goods we accept having to accept our goods on the same terms. "free trade" was always supposed to have "fair trade" safeguards. Another issue was supposed to be that workers in all countries were supposed to have life sustaining wages and safe non-exploitive working conditions.
I don't agree with him on that. Labor costs are a small percentage of the cost of producing a unit of product. What determines where a company manufactures a product is taxes and regulation, those are the big costs. Lower our taxes and regulation here and our companies won't have to worry about third-world working conditions because they'll be able to stay here.
