Being a sharecropper or raising cotton in 1875 in Mississippi is exhausting, demeaning and destroys personal initiative. Being a share cropper might mean that you will have a little something left over for yourself if you have a very good crop. But without good crops, you will have nothing. My family and I work in the fields from sun up to sundown. We don’t own the land we work on. Our owner lets us grow crops on his land and takes a percentage of any profit. Sometimes we make enough money to have enough to eat and clothe ourselves. But it is more often that we just barely scrimp by. We eat what we can grow and on occasion, we can kill a chicken that we have raised. It is not a life you would wish on anyone.
I wonder whether there would be also other options, but one very important aspect is the smog: the city center is where many industry-relevant things meet: the factories are all around it, transport, cars... and since it is surrounded by bad air, the air takes longer to dissipate. This is especially visible if the city is in a valley, such as Mexico city foe example.
Pargo v. Elliot--this case was the beginning of women arguing they do not receive equal treatment to other prisoners.
Though the case was overturned and no just cause was found, it did bring attention to the issue of treatment of prisoners. In particular, women prisons being so few have been cited as having poor health programs and not as many educational programs as men.
I don’t know what timeline map you have, but it was for the expansion of American Democracy.
