I mentioned on the travel thread, but I just got back from NYC where I saw the Aaron Sorkin and Jeff Daniels as Atticus Finch updated interpretation of To Kill a Mockingbird, on Broadway.
There were a lot of updated sensibilities and contemporary nods (to Trump/2019) and some one-liners that drew applause or laughter with regards to those nods, but it seems that by and large the sentiments found in that book 50 years ago are playing out today and your post reminds me of that. Atticus needed his fellow working white class people to do the right thing, etc. That was their moment to shine and make a difference, etc.
Not germane to this post or the political thread, but I found this rendition to better than the original though because Atticus is portrayed a reductive, passive white man of the kind that MLK decried in his Letter from a Bham Jail, who has to be shaken out of his complacency from the black housekeeper who is given agency.
Also one of the lines that helped me to understand even modern day racism was when Scout was questioning about Bob Ewell, "why are they still so upset and bitter about the civil war, it happened 80 years ago" and Atticus says, "Yesterday. It happened to yesterday to him and lots of others like him. They feel it like it was yesterday."
I think we live in a society where a lot of people are still thinking of "yesterday".
