A couple weeks ago, Louisiana Governor Bobby Jindal issued an executive order directing state officials to monitor travel between West Africa and his state, while also prohibiting recent travelers from leading a normal life—like not being able to visit grocery stores. The federal government has not done enough to “prevent the entry of the Ebola virus disease into the United States of America,” Jindal asserted while warning of a potential “public health emergency” stemming from the virus’ ability to spread from one infected person to many others. Governors in other states, including Chris Christie in New Jersey and Andrew Cuomo in New York, followed suit with draconian executive actions targeting Ebola. Here in Maine, the state is prepared to go to court to force a nurse—who has tested negative for the virus—to be quarantined.

People in Louisiana, Maine and around the nation are irrationally paranoid about this disease. The quarantine orders are sure to ignite more controversy, more fear and inspire more states to treat the one Ebola-related death and two transmissions within the United States as a state of emergency. Given that some in the conservative media have taken to calling Obama “President Ebola,” I am tempted to think that the orders and other elite calls for strict containment are purely cynical and cheap political stunts. 

Let’s pretend that, contrary to all expert opinion I’ve heard, Ebola is more than a negligible threat to the United States and that something must be done about it beyond the capabilities of our existing public health institutions. If so, Jindal’s actions and insinuations—coupled with the rants of other far-right politicians and pundits—fit perfectly with the conservative narrative as of late. Got a problem? Seal the border.

Tea Party-style populists who claim to support a free market invariably leave their convictions at the border. Too few jobs? Seal the border and keep manufacturing here. Illegal drugs being imported? Seal the border and shoot everyone heading north in a speedboat near San Diego. Refugee children from Central America seeking a peaceful existence? Seal the border and send them right back to their parents. Working in Washington this summer, one of the more unbelievable calls I received was from an individual worried about little immigrant children bringing Ebola across the border as part of an intricate ISIS plot. The caller demanded that the government immediately act to seal the border. He said that no elected official in Washington would receive his vote unless they immediately grabbed a gun and went down to defend the border. Sealing the border, the narrative goes, keeps America America—to hell with everything else.

The problem here is that sealing the border is incompatible with a globalized society and an international market economy. In such a world, border closures are rarely a good way to deal with anything—even a scary disease with a slim chance of exposure. Closing borders inhibits the exchange of goods and ideas, leading to lower output. Closing borders promotes xenophobia and encourages a jingoistic dislike of people and cultures. Closing borders furthers an us-versus-them mentality that degrades cooperation, reduces trade and closes off opportunities for our own people and for human beings around the world. America is what it is today in large part because of its interaction with the rest of the world, not in spite of it. I, alongside other more liberally inclined commentators, never tire of reiterating that the U.S. is a nation of immigrants and that most of our border-crazy counterparts badly need a history lesson.

Nigeria recently solved its Ebola problem. It did not do so by closing its borders. It did so by quickly identifying the sources of the disease and quarantining infected patients. It did so by smartly tracking how the disease entered the country and identifying who could have caught it. Nigeria does not have nearly as advanced a public health infrastructure as the United States, and it has managed to solve its own Ebola crisis. It did not need to resort to absurd, isolationist measures to remove the disease from its country.

We live in an open society. Admitting outsiders and foreign goods has never destroyed America. In fact, in almost all cases, it has enriched our country. We are a nation that imports goods from many countries, then sends a crate of our own products back. We bring students, workers and refugees from all corners of the world, and then our own children go abroad to learn and contribute in other parts of the globe. Panic-driven isolationism will never solve our nation’s problems. Instead, we must share information, goods and services with as many people and nations as possible to gain a deep understanding of the problems facing us. Then—inside our borders and out—we will prevail.
