Many Chinese manufacturers of consumer products are so obsessed with shoveling products out the door that they cut dangerous corners in order to keep their selling prices down. First it was lead in children's toys. Then faulty materials in wallboard that made several hundred U.S. homes uninhabitable because of mold and noxious odors. More recently it has been deadly cadmium in children's jewelry. Why do Chinese manufacturers use toxic materials in their products? It's cheaper.
