Different economic systems are based on different ideas of what it means to be human and what motivates us. The Old Testament in Christianity reflects a negative view of humanity, while the New Testament focuses on love and the idea of a common humanity. Capitalism, is based on the idea that greed and self-interest drive individuals and the market, while socialism is based on the idea that solidarity and cooperation are what motivate people.
This division between different ideologies and worldviews is a long-standing one. Understanding the underlying assumptions about human nature can provide a useful framework for examining and critiquing different economic systems and ideologies, and help us make informed decisions about the kind of society we want to build.
