In recent weeks, the Trans-Pacific Partnership (TPP) is back in the news. TPP aims to lower barriers to trade among the United States and a variety of other nations including rich countries like Japan, Canada, and Australia and developing countries like Chile, Peru, Vietnam, and Malaysia. US Senator Elizabeth Warren (D-MA) has come out strongly against TPP, as has senator and presidential candidate Bernie Sanders (D-VT). President Barack Obama continues to support TPP–he recently succeeded in having the agreement fast-tracked by the senate and will likely replicate that success in the house. Once TPP is fast-tracked, congress cannot debate the treaty’s contents or make amendments to it. Is TPP good for the United States? Who is right?
