Over two billion people worldwide live in poverty, suffering from hunger, oppression, and war. More than 65 million of them were displaced just last year, many hoping for a better life in Europe or North America. Urgent help is needed - but are open borders the right answer to the world's misery? This view has many advocates, yet philosopher Julian Nida-Rümelin is convinced: Open borders would not significantly alleviate suffering; instead, they would further weaken the regions of origin and exacerbate social conflicts in the host countries. They are not a solution to the shameful humanitarian scandals of our time. In his Ethics of Migration, Nida-Rümelin bridges the gap between philosophy and politics: Political action must be based on the values and norms of humanity. Only then can responsible solutions be found.
