If the Trans-Pacific Partnership (TPP) negotiations ever conclude, the agreement will bring major benefits to the economies of 12 Pacific Rim countries, including the United States.

But as trade policy analyst Bill Watson notes, TPP supporters constantly focus on the narrow benefits the agreement will bring to special interests.
