Problem: The US has lost some of its competitive advantage with companies in other countries. A major part of this problem is the differences in economic policy and labor standards that prevail in various countries.
Solution: Set specific global Tariff Triggers. For example: 5% on countries that peg their currency, 10% on countries that allow child labor, 10% on countries that outlaw organized labor, etc. These numbers are just examples. The triggers should be set to offset some of the unfair competitive disadvantage.
Benefits: US workers will be competing more fairly with international competitors.
Some foreign countries will improve their labor standards in order to avoid tariffs on their exports. In those cases, US workers will benefit because the foreign competition will have have to operate under similar rules as US companies.
Some foreign countries will not change their labor standards or economic policies, so they will trigger the tariff. This will also protect US workers from those unfair practices (to some degree) because import tariffs drive up the prices of those specific competing imports.
