Final answer:
The sociologist described in the question is taking a functionalist approach, which views social inequality as useful rather than harmful for the overall functioning of society.
Step-by-step explanation:
The sociologist described in the question is taking a functionalist approach.
The functionalist perspective in sociology views society as a whole unit, made up of interrelated parts that work together to ensure the continued health and viability of the whole. It believes that social inequality serves a purpose in society and promotes the idea that people train for and fill the most demanding and highly regarded statuses.
An example of this perspective is the belief that social stratification, including social inequality, exists to motivate individuals to pursue higher education and strive for prestigious positions in order to benefit the overall functioning of society.
