Step-by-step explanation:
Intergenerational social mobility refers to the ability of individuals to move up or down the social ladder compared to their parents or grandparents. It is often measured using earnings as a proxy for social class. The question suggests that the United States has the greatest intergenerational social mobility in terms of earnings among Western countries.
This claim is supported by research that compares social mobility across different countries. It is important to note that social mobility can be influenced by various factors such as educational opportunities, occupational mobility, and social policies.
For example, studies have shown that the United States has higher income mobility compared to countries like the United Kingdom and France. However, it may not necessarily have the highest social mobility in all aspects, such as educational mobility or income mobility across all income levels.
