The Migration Driven by Developed Countries

LAGOS—About a year ago, Dolapo Oni appeared to have it all. Then he resigned and moved with his family to Canada, eventually getting a job as an investment associate in a wealth-management firm in Calgary. In some ways, Oni’s story (and that of his successor in Lagos) is not unusual: a skilled professional leaves a job at home in search of work in wealthier parts of the world, betting that the short-term instability of uprooting an established life will be worth it in the long term.
