Rather than a public system where all Americans have health insurance in exchange for paying higher taxes, health insurance is offered to Americans through private companies. A sociologist observes that the private system seems locked in place because insurance companies fund lobbyists who successfully oppose efforts to create a public system. Which of the following concepts describes the development of the healthcare system in the United States?

A) A social movement

B) Life course

C) Critical mass

D) Path dependency

The correct answer is D, Path Dependency. Path Dependency is a term used to describe something that is affected by previous events or choices that have been made. In this case, the healthcare system being stuck in a loop is because of the fact that there are events that are affecting each other as explained in the path dependency theory.
