How is the awareness of the white community's heritage similar and different from that of Beneatha and her African heritage?

Beneatha is Walter's 20-year-old sister, a college student who invades the Younger household with her modern ideas and philosophies on race, class, and religion. She is a handsome intellectual who has worked hard to refine her speech. She feels that the white "heritage" of wealth and entitlement should be open to blacks as well.
