The Wall Street Journal reports on the shortage of nurses in Ghana, Africa. More than 500 left the country last year, most to take higher-paying jobs in wealthy countries. Nurses in Ghana, a poor country, earn about $75 a month. Last year's departures were nearly triple the 1999 total and more than double the number of nursing graduates Ghana produced in 2000. Furthermore, the global flow of nurses, from poor to rich lands, reflects the way talent today goes to the highest bidder, regardless of national borders. This rewards talented people, of course, but adds to the problems of health-care systems in many poor nations.
