Healthcare in the United States is a complex and multi-faceted system that is largely controlled by the government and private entities. The federal government exercises considerable control over the healthcare system by setting regulations and providing financial aid, while private insurers and providers also have an influence. At the state level, governors and legislatures have the power to pass laws and shape policy, while healthcare providers, such as hospitals and physicians, also have a role to play. Ultimately, the combination of federal, state, and private control determines the healthcare system in the US.
