It is obvious that Mrs. Dashwood has more desire to act correctly by their family relationship than either of the John Dashwoods. I wonder if they, particularly Mrs. John Dashwood, thought that was because Mrs. Dashwood did not want to cast aside rich relations?

I do not think that Mrs. John Dashwood cares much for family, for family's sake; for duty, for responsibility (except as the world might disapprove her acting contrary to it), or for the value someone might have irregardless of wealth and position.
