“When educated people emigrate, they leave with skills and experience crucial to solving their countries’ critical problems. The migration of doctors leaves poor countries (and eventually other global population centers) subject to the ravages of highly communicable diseases. Public services are deprived of trained personnel, and countries lose revenue from some of their highest-earning taxpayers. Sending countries also lose educated citizens who otherwise might play key roles in developing responsive governments and organizing civil society, often resulting in political instability and regional conflict.”
