Migration matters. Economic growth depends on productivity, and the most productive people are often the most mobile. A quarter of America’s engineering and technology firms founded between 1995 and 2005 had an immigrant founder, according to Vivek Wadhwa of Harvard Law School. A quarter of international patent applications filed from America were the work of foreign nationals. And such measures ignore the children of immigrants. Jeff Bezos, the founder of Amazon, is the stepson of a man who fled Cuba at the age of 15 and arrived without even a high-school diploma.
So a country’s economic prospects depend in large measure on whether it is a place where people want to be. Desirable destinations draw talented and industrious migrants. Less desirable ones suffer a brain drain. Desirability is tricky to measure, however.
