The layering of people into massive groups based on their control over resources is called "social stratification." Social stratification refers to the hierarchical arrangement of individuals in society, often based on factors such as wealth, income, education, occupation, and power. This system of categorization leads to the division of society into classes, where individuals belonging to different strata have varying access to resources, opportunities, and privileges.

In many societies, social stratification results in inequalities that can impact individuals' quality of life and limit their social mobility. It can manifest through economic disparities, with wealthier individuals gaining more influence and power compared to those with fewer resources. Social stratification is a complex phenomenon influenced by historical, cultural, and social factors, and it can vary from one society to another. Understanding this concept is crucial for analyzing social issues, as it highlights how resources and opportunities are distributed unevenly across populations.
