Final answer:
The statement is true; the majority of people with private health insurance in the United States are covered under some type of managed care system, often through employer-based plans or the Affordable Care Act's health exchange markets.
Step-by-step explanation:
The statement that the majority of people with private health insurance have some type of managed care is true. In the United States, the health insurance landscape is such that most individuals who are covered through private health insurance are indeed part of a managed care system. This approach is prevalent mainly because it is seen as a method to combat the adverse selection problem by having groups of people—both high risk and low risk—insured together, which is common through employer-based group plans or through plans purchased on the health exchange markets established under the Affordable Care Act.
Additionally, employers often provide health insurance as part of their benefits package, although this is not as common among small companies or those that pay lower wages. The government provides alternative forms of health insurance, such as Medicare for those over sixty-five and Medicaid for the poor and disabled, but these do not cover all Americans. There were around 31-32 million Americans without health insurance in recent years, highlighting the ongoing challenges within the U.S. health care system.
