What is the theme in Marjorie Morningstar by Herman Wouk?

Generational conflict is the main theme of the story. An old and almost overused theme in literature, author Wouk highlights the clash of generations as he depicts the ongoing conflicts between Marjorie and her parents, especially her mother. Stereotypical of Jewish mothers for decades, Rose Morgenstern has one goal for he daughter, that is, marriage to an appropriate Jewish boy, preferably a doctor or lawyer. Almost every young man who meets mother's expectations and approval, however, is ultimately rejected by Marjorie.
