Final answer:
The perspective that emphasizes individual effort as the key determinant of success, commonly related to the American Dream, is known as individualism.
Step-by-step explanation:
When someone says that an individual member of a minority group will succeed if they try hard enough, they are speaking from an individualistic perspective. This viewpoint aligns with the concept of the American Dream, which suggests that personal success is primarily the result of individual effort. It emphasizes personal responsibility and effort over structural or societal factors. This perspective is often contrasted with cultural determinism, which would attribute success or failure to cultural or societal influences, and structural functionalism or conflict theory, both of which would take into account the role that social structures play in determining individual outcomes.
