Why are some people free to move around the world while others are constrained for crossing borders? This book challenges this crucial injustice that creates inequalities in the face of global issues such as climate change, wars, diseases and other local risk factors. The main theme of this collective work is to consider the representation of human displacement as a moral barrier between expatriates and migrants, with the former being seen as 'unproblematic' and 'desirable' while the latter is portrayed as 'problematic' and 'undesirable'. Surveys show that this binary categorization subsists on at least four continents, stigmatizing different categories of people.
