Even seventy years later, it is obvious why John Steinbeck won the Nobel Prize for Literature. The writing is emotional and engaging. The book alternates between chapters reporting the broad picture and specific chapters about the Joads, their hopes and dreams, theie efforts and failures.
The book has two main themes. First, the Okies, migrant farm workers, are people and not the dehumanized animals depicted by the land owners, food processors, police and towns people. Second, these people need to organize to address their situation, because no one else will help.
What has happened in the last seventy years? Migrant farm workers are still demonized by their opponents, but thirty-to-forty years after The Grapes of Wrath, the farm workers finally organized and made some progress to improve conditions.
In addition to these broad issues, the book also illustrates some enduring American values.
