The U.S. government provides healthcare for people under 65 with neither private insurance nor wealth through programs like Medicaid and Medicare.
Step-by-step explanation:
For people under 65 with neither private insurance nor wealth, the U.S. government provides healthcare through programs like Medicaid and Medicare. Medicaid is designed to provide health care to individuals with low incomes, while Medicare is available to those over the age of 65. These government-funded programs aim to ensure that individuals who cannot afford private insurance still have access to essential medical services.
