Through the Darcy-Elizabeth and Bingley-Jane marriages, Austen shows the power of love and happiness to overcome class boundaries and prejudices, thereby implying that such prejudices are hollow, unfeeling, and unproductive. Of course, this whole discussion of class must be made with the understanding that Austen herself is often criticized as being a classist: she doesn’t really represent anyone from the lower classes; those servants she does portray are generally happy with their lot. Austen does criticize class structure, but only a limited slice of that structure.
