Answer:
C. Medicaid helps many people afford medical treatment.
Step-by-step explanation:
Medicaid is a public health insurance program created to help people with low income, families with children, pregnant women, the elderly, and people with disabilities afford medical treatment. It's estimated that about 1 in 5 Americans rely on Medicaid's help for treatments they otherwise wouldn't be able to afford. This is why statement C is the correct one.
Statement A is incorrect because not everyone in the US can afford health insurance.
Statement B is incorrect because the government has created numerous programs to help people who can't afford medical treatment.
Statement D is incorrect because there are many private HMOs (health maintenance organizations), not only those offered by the government.
