Read the following excerpt from chapter 21 of John Steinbeck's The Grapes of Wrath: Those families which had lived on a little piece of land, who had lived and died on forty acres, had eaten or starved on the produce of forty acres, had now the whole West to rove in. And they scampered about, looking for work; and the highways were streams of people, and the ditch banks were lines of people. Behind them more were coming. The great highways streamed with moving people. There in the Middle and Southwest had lived a simple agrarian folk who had not changed with industry, who had not farmed with machines or known the power and danger of machines in private hands. They had not grown up in the paradoxes of industry. Their senses were still sharp to the ridiculousness of the industrial life. And then suddenly the machines pushed them out and they swarmed on the highways. The movement changed them; the highways, the camps along the road, the fear of hunger and the hunger itself, changed them. The children without dinner changed them, the endless moving changed them. They were migrants. And the hostility changed them, welded them, united them—hostility that made the little towns group and arm as though to repel an invader, squads with pick handles, clerks and storekeepers with shotguns, guarding the world against their own people.
