Social insurance is a government program designed to provide financial support to individuals during times of need, such as retirement, disability, or unemployment. It is funded through taxes collected from workers and employers, ensuring that everyone contributes to a safety net that helps protect citizens from economic hardships. Common examples of social insurance programs include Social Security, Medicare, and unemployment insurance. These programs aim to promote social welfare by offering benefits that help people maintain a basic standard of living. By pooling resources, social insurance helps reduce poverty and provides a sense of security for individuals and families during challenging times.
