The magic of diasporas

A recent article in The Economist:

Immigrant networks are a rare bright spark in the world economy. Rich countries should welcome them.

"fears that poor countries will suffer as a result of a “brain drain” are overblown. The prospect of working abroad spurs more people to acquire valuable skills, and not all subsequently emigrate. Skilled migrants send money home, and they often return to set up new businesses. One study found that unless they lose more than 20% of their university graduates, the brain drain makes poor countries richer."
