A social pyramid is a term used to describe the hierarchical structure of a society or community, with the most powerful and wealthy individuals at the top and the poorest and most vulnerable members at the bottom. There are several synonyms for social pyramid, including social hierarchy, social stratification, class structure, and social order. These terms all refer to the way in which a society is organized based on power, wealth, and social status. While the social pyramid may differ from one culture or society to the next, the general concept remains the same - those with the most power and resources always hold a position of privilege at the top.
