A class system is a social hierarchy that categorizes individuals based on factors such as wealth, occupation, education, and social status. This system often divides society into different classes, such as the upper class, middle class, and lower class. Each class typically has distinct lifestyles, values, and opportunities, influencing individuals' access to resources and power. Class systems can vary significantly across cultures and historical periods. For example, in some societies, caste systems may exist, where social mobility is limited, while in others, such as capitalist societies, individuals may have more opportunities to move between classes based on their achievements and economic success.
