Every day newspapers in the Western world carry articles about illegal immigrants, asylum seekers and other migrants. The focus of these articles varies greatly from migrants as a threat to one or another important social or societal interest, to migrants as an important asset to those same interests. The tone is most often emotional - whichever way the focus goes. The overall impact is to confuse: is migration good or bad? In this book Guild and van Selm seek to investigate these value assessments regarding migrants in Europe, the USA, Canada and Australia. While looking at issues such as security, human rights, legal systems, identity, racism, welfare, health and labour, the authors also respond to critics of immigration.
