Family is portrayed in A Raisin in the Sun as an incredibly discrete unit that must project a certain image in the world. Within the family, relatives may quarrel, nag, and insult each other, but when guests come over, certain proprieties must be observed. A Raisin in the Sun explores these complex family dynamics. Furthermore, this theme intersects with Dreams, Hopes, and Plans as children in a family inspire dreams and keep them alive.
In A Raisin in the Sun, familial unity is mistaken for familial obligation, causing Walter to resent his family for holding him back from his dreams.
Although Walter yearns to attain the American Dream through capitalism, the characters in A Raisin in the Sun ultimately find hope for their future not in money, but in solidarity as a family.
