How was farming changed according to chapter 19 in The Grapes of Wrath by John Steinbeck?

In Chapter 19 of The Grapes of Wrath, farming undergoes significant changes due to the economic hardships and mechanization brought on by the Great Depression. Many small farmers are driven off their land by large agribusinesses that prioritize profit over people, leading to the loss of traditional farming practices and community ties. The introduction of machinery replaces manual labor, further displacing workers and contributing to the decline of family-owned farms. This shift reflects broader themes of exploitation and the struggle for survival in a rapidly changing agricultural landscape.
