Even at the beginning of the 21st century, a large part of humanity lives in bitter poverty. This raises the pressing question of what citizens of wealthier countries morally owe to extremely poor people. Valentin Beck addresses this within the framework of a comprehensive theory of global responsibility. In his brilliantly written book, he tackles central questions of global justice theory, conducts a detailed analysis of our entanglement in global social structures, and sheds new light on one of the greatest moral challenges of our time. The central demand of this study is that we need to rethink our political and individual approaches to global poverty.
