The U.S. healthcare sector is a major contributor to economic output, accounting for 17% of the nation’s GDP—more than any other country, according to the WHO. While most healthcare facilities are privately owned, some operate as non-profit, for-profit, or government-run institutions. Publicly funded programs like Medicare, Medicaid, CHIP, and the Veterans Health Administration play a significant role, with 64% of health spending covered by the government. Most public sector employees receive health insurance through these government programs.
Despite high spending, the U.S. faces serious health challenges, including high rates of obesity, heart and lung disease, and cancer. In 2012, one in four seniors faced bankruptcy or had to mortgage their homes due to medical costs. The Affordable Care Act (ACA) was introduced to address these issues by pushing hospitals and physicians to improve outcomes, reduce costs, and enhance accessibility through financial, technological, and clinical reforms.
