The United States once had open borders. Migrants from all over the world would arrive fleeing war, escaping poverty and seeking opportunity. Open borders made our country strong. But many Americans today are horrified — or frightened — by the idea of “open borders.” Harsh new immigration policies are making it more difficult than ever to come to the U.S. or even ask for asylum. Nevertheless, violence, oppression, poverty, desperation, and hope continue to drive migrants to our borders. Last year, more than 1,000 migrants from Central America gathered near the border of Guatemala and Mexico to travel north in search of asylum. Radical Imagination host Angela Glover Blackwell sits down with Roberto Corona, founder of People Without Borders, an organization that assisted this refugee caravan. We also hear from New York Times Columnist Farhad Manjoo, who has called for open borders.
