In primitive society, when social productivity was very low, and people's labor income had little surplus except to maintain their own survival and reproduction, there was no so-called concept of human rights. Later, with the development of productive forces, the emergence of private ownership produced Class opposition and class oppression. With the emergence and development of slavery, the right of slaves to exist as the oldest human rights requirement was raised for the first time. Therefore, without the development of productive forces, no human rights problems will arise. This passage mainly supports the argument that:. ['Human rights requirements are accompanied by the emergence of classes.', 'The right of slaves to live is the oldest human right.', 'Development of productivity leads to human rights requirements.', 'Private ownership is at the root of the emergence of human rights.']
