This book packs so much information and analysis in barely over 200 pages. Walia analyzes how capitalist exploitation manufactures displacement and the way migrants are seen simultaneously as undesirable excess population and ultra exploitable source of (permanently) temporary labour. She writes that borders are not merely lines drawn on a map but not internal and external active productions of the state that use citizenship as a means to segregate and racialized populations within and without. Or course, capitalism and imperialism are the crux of the issue, and anti capitalist struggles must include these highly vulnert groups of people who are displaced due to imperialist exploitation.
