With workers the focus, Wilson draws attention to parallel processes of labour mobility to mobile capital (from the 1970s), such that about 150 million people are global migrant workers. Chapter 12 examines the concept of ‘superdiversity’ in the labour markets of rich democracies, with its positive welcoming but exploitative underside. Although many non-migrants are also exploited, evidence shows super-exploitation for migrant workers.
