Children from which social classes are more likely to develop skills related to managing and resolving conflict between peers?

Children from working class.

Explanation:

According to Peter Callero's book "The Myth of Individualism: How Social Forces Shape Our Lives", working-class children do not usually spend time after school engaged in formal activities. Their play time is structured and decided by themselves. They come up with games, rules, and decide when to stop playing. That helps develop a set of skills, including managing and resolving conflict between peers. On the other hand, middle-class children tend to spend time in activities designed and assessed by adults, which leads to a different set of life skills.
