[...] Seven years after the fall of the Taliban and the establishment of a civilian-led, internationally backed government, Afghanistan remains one of the poorest countries in the world, with rates of unemployment, illiteracy, infant mortality and malnutrition on a par with the most impoverished nations in sub-Saharan Africa. Most homes lack light, heat and running water; most babies are born at home and without medical help. Now, according to U.N. figures, the populace is getting even poorer. A combination of drought, soaring food prices, scarce jobs and meager wages has meant that about 5 million Afghans -- far more than in any recent year -- are slated to receive emergency food aid. Many families spend up to 80 percent of their income on food. [...] "People are really feeling the gap between rich and poor now," said Ebadullah Ebadi, a spokesman for the World Food Program here. "Once there were three classes in Afghanistan: the rich, the middle and the poor. Now those in the middle are joining the poor, and prices are rising so high that people can't feed their families on salaries that once allowed them to educate their children and even save a little money."
