The younger members of the Younger family are Walter and Beneatha. Like many siblings, they often argue and treat each other badly, but they also love each other underneath.
Walter and Beneatha struggle because they look at life through a different set of lenses. Walter wants to adopt US society's typical male role of head of household and provider of a comfortable life for his family, but he feels he has been thwarted in this because of his race. His goals are self-oriented: he wants to run a successful business so that his son, wife, and community will look up to him with respect.
Beneatha doesn't like Walter's idea of owning a liquor store. On the other side, Walter thinks it is a waste for Beneatha, a woman, to go to medical school and believes she should settle for being a nurse—or marry the wealthy George Murchison. She clashes with him because she has far more idealistic goals and wishes to help the Black community as a whole. She also gets very angry with Walter when he is cheated of the money earmarked for her education.
Walter and Beneatha clash because they represent different goals held by young people in the Black community.
