Immigration restrictions and border controls function are a legal form of discrimination. Open Borders writes, "Immigration restrictions are similar to apartheid and Jim Crow laws, but their main criterion of discrimination is not race but place of birth/origin."
We should abolish borders because discrimination based on something arbitrary categories, such as race or birth/origin, is morally wrong.
While border controls exist to protect national security, national leaders often couple anti-immigrant, racist language with promoting border control.
Borders promote anti-immigrant discourse, xenophobia, and racism. Border controls seem necessary because of the idea that people who are different should be kept out. We should abolish borders to bring societies a step closer to understanding one another rather than hating one another based on cultural or national differences.
People in countries with fewer social infrastructures live with a lower minimum wage, greater passport restrictions, less social security, and a poorer quality healthcare system than that which people in more economically developed countries enjoy. Yet, such disparities exist because of borders, as seen in the drug trafficking and corruption problems between the U.S. and Mexico.
Abolishing the border controls would decrease violence and allow Mexican migrants to work and earn a living in the US to better their families in Mexico.
Free migration should be available to all people. Free migration complements Article 13 of the Universal Declaration of Human Rights: "(1) Everyone has the right to freedom of movement and residence within the borders of each state. (2) Everyone has the right to leave any country, including his own, and to return to his country."
