What are the advantages and disadvantages of being Aunt Alexandra in To Kill a Mockingbird by Harper Lee?

Aunt Alexandra is not one of the more flattering
characters in To Kill a Mockingbird. She is haughty and
domineering, and she dominates her hen-pecked husband, Jimmy, who is rarely mentioned or
seen. Alexandra inherited the Finch Landing homestead when brothers Atticus and Jack
moved away, so she is apparently financially secure. She normally travels with a Negro
chauffeur, and she prides herself on her family upbringing, clothing and
high-handed manners. She has few motherly skills, and the children (as well as Atticus)
seem to prefer Calpurnia's parenting abilities. Alexandra seems to enjoy her stay in
Maycomb, and "Maycomb welcomed her." She finds the social life, with its parties and
church gatherings, to her liking, and she fits in "as if she had always lived with
us." Scout and Jem are barely able to tolerate her, and when she tries to convince
Atticus to fire Calpurnia, he strongly rebukes her. However, late in the story, she
shows some likable traits. She thanks Miss Maudie for defending her at the Missionary
Circle tea, and sympathizes with Atticus following the Tom Robinson trial. She worries
about Jem and Scout going to the Halloween banquet alone and blames herself when the
children are attacked by Bob Ewell. She is genuinely kind to Scout afterward, calling
her "darling" and laying out the clothing she detests most: Scout's
overalls.
