Final answer:
Aunt Alexandra opposes Scout inviting Walter Cunningham over due to her views on social hierarchy, believing the Cunninghams are beneath the Finch family.
Step-by-step explanation:
Aunt Alexandra does not want Scout to invite Walter Cunningham to their home because she has a strong sense of social class and does not consider the Cunninghams to be on the same social level as the Finch family. Alexandra has prejudiced views on families in Maycomb and believes in maintaining social distinctions.
Despite Atticus's more egalitarian views, Alexandra enforces her perspective on Scout and emphasizes the importance of associating with the "right" people.
In Harper Lee's novel To Kill a Mockingbird, Aunt Alexandra does not want Scout to invite Walter Cunningham to their home because the Cunninghams are a poor and socially lower class family.
Aunt Alexandra is concerned about maintaining their social standing and believes that associating with the Cunninghams would reflect poorly on their reputation. She values class and social status, and believes that Scout should only befriend people who are similar to their own family.
