People wait in line to enter a small market to try to buy items like disposable diapers, laundry detergent and razors in downtown Caracas, Venezuela. The falling oil prices that are providing relief to drivers around the world threaten to bring misery to the lives of millions of Venezuelans, whose country depends almost exclusively on oil revenue. Many products have already been in short supply due to price restrictions and currency controls put in place by the socialist government long before the slide in petroleum prices. Now Venezuela is suddenly a lot less rich, and many fear those lines will just get longer.
