On the other hand it showed the human generosity of spirit , sharing food when they themselves were starving, for example. It starkly revealed the inability of uneducated to know how to face problems. It illustrated stubborn refusal to stick on " their land" when it wasn't their land, and if they could have stayed , they would have died of starvation
The suffering blamed the greedy for their plight but it was more than that , how many see this? It was lack of knowledge about farming, inability to switch crops, lack of education, living day to day subsistence . It was plain and simple an agrarian society that had no place to go ,nothing to do except migrate and follow the promise of a dream,just as our ancestors did thru history whether Stone Age or agrarian. only the industrial revolution freed us from direct contact with the land and provided food for more people because we had the ability to do more with machines.
Interesting how some people see and feel only the negative and miss the learning situation, the loving, the giving in spite of suffering and loss. It's hard living but then we encounter this today and it requires problem solving as our leaders tried to do during the Great Depression with programs that produced actors , producers and writers of the 40's .
I happen to be reading at the same time the biography of Burt Lancaster and his family struggle at the same period of time in New York
