In Chapter 19 of The Grapes of Wrath, John Steinbeck uses various rhetorical strategies to emphasize his belief in the cycles of human interaction. He first begins his argument by commenting on how California had once belonged to Mexico until greedy Americans, driven ravenously by Manifest Destiny to control North America from sea to shining to sea, began squatting on the land of the Mexicans; after generations, the land was assimilated to the white men, and the Mexicans were paid meager wages for meager work. Steinbeck uses the history of California to run a parallel between the Americans, originally immigrants to the land of California, and the Mexicans who originally owned the land of California. After the whites had assimilated California and established themselves as wealthy landowners, a new kind of immigrant began to migrate to California; although the immigrants bare the same colored skin as the white landowners, they are treated like a disposable resource, much like how the Mexicans likely felt when the whites conquered their land. The entire chapter is essentially an extended comparison of the cyclical nature of man; whoever is in control at the time, they tend to take thorough control and abuse the minority, less wealthy class. Steinbeck truly uses the parallelism to display an unfortunately bleak perspective on the repetitiveness of human interaction.
