...In early 2006, the United States Committee on Refugees and Immigrants estimated that a full 40% of Iraqi's professional class had left the country, taking with them their irreplaceable expertise. Universities and medical facilities were particularly hard hit, with some reporting less than 20% of needed staff on hand. The oil industry suffered from what the Wall Street Journal called a "petroleum exodus" that included the departure of two-thirds of its top 100 managers, as well as significant numbers of managerial and professional workers.
Even before the huge 2007 exodus from Baghdad, the United Nations Commissioner of Refugees warned that "the skills required to provide basic services are becoming more and more scarce," pointing particularly to doctors, teachers, computer technicians, and even skilled craftsmen like bakers.
By mid-2007, the loss of these resources was visible in the everyday functioning of Iraqi society. By then, medical facilities commonly required patients' families to act as nurses and technicians and were still unable to perform many services. Schools were often closed, or opened only sporadically, because of an absence of qualified teachers. Universities postponed or canceled required courses or qualifying examinations because of inadequate staff. At the height of an incipient cholera epidemic in the summer of 2007, water purification plants were idled because needed technicians could not be found.
The most devastating impact of the Iraqi refugee crisis, however, has probably been on the very capacity of the national government (which de-Baathification and privatization had already left in a fragile state) to administer anything. In every area that such a government might touch, the missing managerial, technical, and professional talent and expertise has had a devastating effect, with post-war "reconstruction" particularly hard hit. Even the ability of the government to disperse its income (mostly from oil revenues) has been crippled by what cabinet ministers have termed "a shortage of employees trained to write contracts" and "the flight of scientific and engineering expertise from the country."
