Social classes are groups of people in a society who share similar economic status, education, and lifestyle. These classes often include the upper class, middle class, and lower class. The upper class typically has significant wealth and influence, while the middle class usually has moderate income and education. The lower class often faces economic challenges and limited access to resources. Social classes can affect individuals' opportunities and experiences in life. Factors such as income, education, and occupation play a crucial role in determining one's social class. Additionally, social mobility allows individuals to move between classes, influenced by personal achievements or changes in economic conditions.
