BUENOS AIRES, Jul 27 (IPS) - Darío is a locksmith in Flores, a traditional middle-class neighborhood in the Argentine capital, who will have to stop working in the next few days. "Suppliers have suspended the delivery of locks, due to a lack of merchandise or because of prices," he laments. His case is an illustration of an economy gone mad in a country that once again finds itself on the brink of the abyss.
