In the realm of  long-term economic things to worry about, there is not much that can rival youth unemployment in the greater Middle East and North Africa. Some years ago, for example, the World Bank  estimated that the region’s population rise was such that jobs needed to grow by some 3.5 percent  per year if unemployment along the lines of one-in-four was to be avoided over the next couple of decades. There has been nothing of great note to change this forecast.
