What's the difference between social security and AFL?

Social security is a system to guarantee citizens' basic life, and the AFL is a joint organization of American skilled workers' unions.

Social security is a system that takes the state or government as the main body, redistributes national income according to the law, and gives material help to citizens when they temporarily or permanently lose their ability to work and have difficulties in life for various reasons, so as to ensure their basic livelihood.

The essence of social security is the pursuit of fairness, which must be based on legislation or law. Its basic contents include social insurance, social relief and social welfare.
