What is Steinbeck's purpose in presenting the scene in which the tractor goes through the dooryard of the tenants' house?

In "The Grapes of Wrath," Steinbeck uses the scene of the tractor going through the tenants' house to symbolize the destructive power of mechanization and capitalism on traditional ways of life. It serves to emphasize the displacement and loss experienced by the tenant farmers, highlighting the larger theme of societal injustices and the impact of industrialization on rural communities.
