The massive disparity between the relative wealth of most citizens in affluent countries and the profound poverty of billions of people struggling elsewhere for survival is morally jolting. But why exactly is this disparity so outrageous and how should the citizens of affluent countries respond? Political philosopher, Thomas Pogge, has emerged as one of the world?s most ardent critics of global injustice which, he argues, is caused directly by the operation of a global institutional order that not only systematically disadvantages poor countries but is imposed on them by precisely those wealthy, powerful countries that benefit the most from the order?s injustice. In allowing their governments to perpetrate this injustice, Pogge contends that citizens of the wealthy countries collude in a monumental crime against humanity. In this book Pogge?s challenging and controversial ideas are debated by leading political philosophers from a range of philosophical viewpoints. With a clear and informative introduction by Alison Jaggar, and original contributions from Neera Chandhoke, Jiwei Ci, Joshua Cohen, Erin Kelly, Lionel McPherson, Charles W. Mills, Kok-Chor Tan, and Leif Wenar, this volume deepens and expands the debate over global justice and moral responsibility in the world today.
