Drawing on his family's own experience emigrating from India to Britain and America, and years of reporting around the world, Suketu Mehta subjects the worldwide anti-immigrant backlash to withering scrutiny. The West, he argues, is being destroyed not by immigrants but by the fear of immigrants. He juxtaposes the phony narratives of populist ideologues with the ordinary heroism of labourers, nannies and others, from Dubai to New York, and explains why more people are on the move today than ever before. As civil strife and climate change reshape large parts of the planet, it is little surprise that borders have become so porous.
