The term "brain drain" refers to the depletion or loss of professional, entrepreneurial, intellectual or technical personnel by one country or region of the world to the benefit of another (it can also occur within a country from rural to urban areas, from poorer areas to richer areas etc). This phenomenon has been said to be most acute in the flow of talent from developing and underdeveloped nations to the first world but it's also been used, more controversially, to allege that there is a flow of talent (managerial and entrepreneurial as well as intellectual and technical) within the first world from Canada and western Europe to the United States where pay is higher and taxes are lower.
