Something tells me that issues associated with the mobility of skill ed workers in science and engineering require a bit more nuance. Perhaps instead of “brain drain” those thinking about “brain circulation” are onto something. Consider the following:

Scientists and policy makers in the United States are worried about a “brain drain.”

Scientists and policy makers in Canada are worried about a “brain drain.”

Scientists and policy makers in South Africa are worried about a “brain drain.”

Scientists and policy makers in Indonesia are worried about a “brain drain.”

Scientists and policy makers across Africa are worried about a “brain drain.”

Scientists and policy makers in Argentina are worried about a “brain drain.”

Scientists and policy makers across Europe are worried about a “brain drain.”

Scientists and policy makers in Pakistan are worried about a “brain drain.”

Scientists and policy makers in Japan are worried about a “brain drain.”

Scientists and policy makers across Asia are worried about a “brain drain.”

Scientists and policy makers in Australia are worried about a “brain drain.”

Has anyone looked in Antarctica for all of these brains?
