Social stratification is the way society is organized into different layers or classes based on factors like wealth, education, and power. These layers can create significant differences in people's lives, affecting their access to resources, opportunities, and social status. For example, individuals in the upper class often have better access to quality education and healthcare compared to those in the lower class. This system can lead to inequality, where some groups, such as racial minorities or low-income families, face barriers that make it harder for them to improve their situation. Understanding social stratification helps us recognize these disparities and work towards a more equitable society.
