This year has seen many issues divide the right and left. There did not seem to be much agreement between Republican and Democratic candidates on education, abortion, LGBTQ rights, guns or healthcare. One issue, however, united people as diverse as Bernie Sanders and Donald Trump as well as president Obama and Congressional Republicans: Protectionism and free trade. Protectionism is the use of tariffs and other trade barriers to undercut foreign competition and bolster a country's domestic industry. Over the last few decades, America has been moving in the direction of free trade through agreements that eliminate trade barriers between the US and other nations. With many lower class and middle class people blaming free trade agreements for the loss of American manufacturing jobs, 2016 saw a pushback against the political establishment on free trade. Donald Trump, breaking with his own party, promised to renegotiate the North American Free Trade Agreement and reject the Trans-Pacific Partnership (which president Obama has lobbied Congress for the approval of). Although she adopted a skeptical position on the Trans-Pacific Partnership Hillary Clinton was burdened with a pro-free trade legacy, including involvement with the TPP as Secretary of State. Trump's victory was aided not only by traditional red states such as Texas and Nebraska, but also by blue states such as Pennsylvania, Wisconsin, and Michigan where factories were once reliable employers for those with less education. Proponents and opponents of protectionism both argue that Their positions are in America's best interest. These arguments are built primarily on economics and mythos.There is one ingredient missing in the discussion about free trade:ethics. I am a utilitarian thinker, meaning that I generally believe what is best for the largest number of people is what is moral. Since utilitarian moral analysis involves the consideration of the quantity of people that benefit from policies or behaviors rather than their nationalities, I reject nationalism as a basis for supporting protectionism. Indeed, prioritizing the prosperity of 318 million people over that of 6 billion others would be utterly immoral. With that said, trade barriers should be used to put pressure on foreign states to enact strong workers' and environmental protections. Trade with countries whose laws are as progressive, if not more so, than the US,(such as the EU,Australia, Canada, Switzerland) should be liberalized with little negotiation.
