Contrary to popular belief, global migration levels have remained relatively stable. So why has it become such a hot button issue on the political world stage? Hein de Haas is a professor of sociology at the University of Amsterdam and an expert in migration. His book, How Migration Really Works: The Facts About the Most Divisive Issue in Politics delves into migration as a historical and ongoing phenomenon, comparing past and present migration patterns. Hein and Greg discuss common misconceptions about migration, why people migrate in the first place, and what the actual impact of migration is on the economy, culture, and climate. *unSILOed Podcast is produced by University FM.*
