What is the importance of the "suburban neighborhoods" mentioned throughout the novel, Mrs. Everything?

There are many suburban neighborhoods in this book, and each one excludes residents based on religion, race, or class. The Kauffmans moved to their neighborhood because, though it is not predominantly Jewish, lower middle class, suburban whites, like the Kauffmans, are displacing the neighborhood's communities of color. The Kauffmans are of a lower socioeconomic class than most of their neighbors, though they have more socioeconomic mobility than the blacks in their neighborhood. The suburb where Bethie Kauffman and her husband, Harold Jefferson, live would not usually welcome an interracial couple. Their socioeconomic class ensures they do not face overt racial discrimination. Comparing the different suburban neighborhoods shows how religion, race, and class affect where one calls home.
