Globalization and Health, The health-care drain

The migration of inhabitants of southern hemisphere countries (commonly called "poor countries") towards the North ("rich countries") deprives these nations of their doctors and nurses. This one-way transfusion can be seen, for example, in movements from Malawi to South Africa and then on to Europe; leaving a vacuum in the poorest countries. Can nothing be done? Perhaps. In Mali, for example, various peripheral economic systems enable certain doctors to stay in the country and treat their compatriots. Helped by international funding.
One surprising instance of globalisation revealing a human face.
