What is the author trying to say about life or people in the story "The Garden Party"?
My impression is that she is trying to see how some people take their necessity for power and ranking, prestige, and financial situation to make everyone else feel less important. Yet, in the character of Laura we find that this is not always the case, because she is a genuinely concerned person who has a true caring feeling for the dead labourer who died the same day she had planned this glorious garden party.
However, we also see the influence of the other ladies on her telling her how it is not her position to care for the laborer, and that the party is more important than the death. Therefore, we see how some people give material things more importance than to the feelings and needs of human beings.
