The United States has a mixture of government-run and private insurance. The government pays most of the cost, but also subsidizes private health insurance through Obamacare. One-third of costs is for administration, not patient care. Health care service providers are private. Sixty percent of citizens get private insurance from their employers. Fifteen percent receive Medicare for those 65 and older. The federal government also funds Medicaid for low-income families and the Children's Health Insurance Program for children. It pays for veterans, Congress, and federal employees. Despite all these, there are 28 million Americans who have no coverage. They either are exempt from the Obamacare mandate or can't afford insurance.
