I guess isolation and social exclusion of different groups is something of relevance. e.g.
- Crooks: racism
- Curley's wife: misogyny
- Candy: ageism
- Lennie: ableism
But I still can't think of any other points that is of relevance to contemporary society.
Not looking for anything over the top. Just looking for a few words or sentences to help me along. I can do all the quote finding and analysis myself.
