Final answer:
Employers are not considered key players in the U.S. health delivery system as they are not a consistent source of health insurance for everyone and are not involved in the actual delivery of healthcare services. Instead, the key system players include healthcare providers, insurance companies, and government programs such as Medicare and Medicaid.
Step-by-step explanation:
The key system players in the U.S. health delivery system include medical care providers, insurance companies, and government programs but not all employers. In the U.S. system, health insurance is often tied to employment, with many Americans receiving coverage through their job. However, not all employers provide health insurance, and thus they are not considered a key player in the health delivery system itself.
Government intervention in healthcare addresses market failures, providing programs like Medicare for those 65 and older, and Medicaid for low-income families. The U.S. system is characterized by its combination of private security and government support, aiming to balance quality, access, and cost. The challenge is to achieve a system where high quality care is available to all at manageable costs.
