With the rapid development of life, the gap between the rich and the poor caused by "some people get rich first" has caused many problems. It is not only the shackle of building a well‐off society in an all‐round way, but also gives many people a "sense of relative deprivation". However, the previous literature mostly focuses on the negative impact of relative deprivation on individual behavior, and lacks the research on it and prosocial behavior. This paper discusses the relationship between relative deprivation and prosocial behavior, and analyzes the role of empathy, just world belief and viewpoint selection.
