Question: Most developed countries have health insurance programs for nearly all citizens. However, not all U.S. citizens are covered by health insurance programs, and thus, equitable healthcare services are not available to all. The U.S. healthcare system is complex and consists of various components that do not always work cohesively, leading to concerns regarding costs, access, and quality. A systems framework provides an organized approach to understanding the various aspects of the healthcare system, including the components and their interactions. Despite various public and private health insurance programs, why are some U.S. citizens without healthcare coverage? Add citations and references
