trade issues One theory is that increased regulation of electronic wastes and concern over the environmental harm in nature economies creates an economic disincentive to remove residues prior to export. Critics of trade in used electronics maintain that it is still too easy for brokers calling themselves recyclers to export unscreened electronic waste to developing countries, such as China, India and parts of Africa, thus avoiding the expense of removing items like bad cathode ray tubes (the processing of which is expensive and difficult). The developing countries have become toxic dump yards of e-waste. Developing countries receiving foreign e-waste often go further to repair and recycle forsaken equipment. Yet still 90% of e-waste ended up in landfills in developing countries in 2003. Proponents of international trade point to the success of fair trade programs in other industries, where cooperation has led to creation of sustainable jobs and can bring affordable technology in countries where repair and reuse rates are higher. Defenders of the trade in used electronics say that extraction of metals from virgin mining has been shifted to developing countries. Recycling of copper, silver, gold, and other materials from discarded electronic devices is considered better for the environment than mining. They also state that repair and reuse of computers and televisions has become a "lost art" in wealthier nations and that refurbishing has traditionally been a path to development. South Korea, Taiwan, and southern China all excelled in finding "retained value" in used goods, and in some cases have set up billion-dollar industries in refurbishing used ink cartridges, single-use cameras, and working CRTs. Refurbishing has traditionally been a threat to established manufacturing, and simple protectionism explains some criticism of the trade. Works like "The Waste Makers" by Vance Packard explain some of the criticism of exports of working product, for example, the ban on import of tested working Pentium 4 laptops to China, or the bans on export of used surplus working electronics by Japan. Opponents of surplus electronics exports argue that lower environmental and labor standards, cheap labor, and the relatively high value of recovered raw materials lead to a transfer of pollution-generating activities, such as smelting of copper wire. Electronic waste is often sent to various African and Asian countries such as China, Malaysia, India, and Kenya for processing, sometimes illegally. Many surplus laptops are routed to developing nations as "dumping grounds for e-waste". Because the United
