According to the National Insurance Act, what key concept is addressed?

The National Insurance Act is primarily focused on establishing a comprehensive social insurance system to cover various risks faced by individuals, such as illness, unemployment, and old age. The key concept it addresses is the creation of a national framework for social insurance, which encompasses various benefits that individuals are entitled to under this system.

This framework provides guidelines and regulations that dictate how benefits are funded, administered, and accessed by the population. It not only includes elements of health insurance and unemployment benefits but also outlines the roles and responsibilities of both the state and individuals in contributing to and benefiting from the system. By focusing on the broader national social insurance frameworks and regulations, the act aims to ensure a safety net for individuals across different stages of life and in various circumstances. This approach emphasizes the importance of a structured and regulated social insurance system for the well-being of the populace.
