Many people in the United States believe that adopting a system for regulating organ trading similar to Iran's will help to decrease the national shortage of kidneys. They argue that the U.S. could adopt similar policies to promote accountability, ensure safety in surgical practices, employ vendor registries, and provide donors with lifetime care. They further argue that private insurance companies would be invested in providing such care for donors, and that laws could be enacted to make long-term care an inviolable condition of any donation agreement.[6]
