We describe a common social phenomenon in this article. It is that when children grow up, in addition to their talents and efforts in comparison with their peers, the parental background between children is also an important stake in their competition. Parents’ social status and superior power will result in more social resources and opportunities for children. We call this phenomenon “parents privilege competition”. The root cause of this phenomenon is the serious hardening of the stratum and the poor social mobility in vertical society, which makes it difficult for children to have an equal competitive environment. After analyzing the phenomenon, this article discusses the causes of this phenomenon and the solutions.
