From The Grapes of Wrath, by John Steinbeck

They arose in the dark no more to hear the sleepy birds’ first chittering, and the morning wind around the house while they waited for the first light to go out to the dear acres. These things were lost, and crops were reckoned in dollars, and land was valued by principal plus interest, and crops were bought and sold before they were planted. Then crop failure, drought, and flood were no longer little deaths within life, but simple losses of money. And all their love was thinned with money, and all their fierceness dribbled away in interest until they were no longer farmers at all, buy little shopkeepers of crops, little manufacturers who must sell before they can make, Then those farmers who were not good shopkeepers lost their land to good shopkeepers. No matter how clever, how loving a man might be with earth and growing things, he could not survive if he were not also a good shopkeeper. And as time went on, the business men had the farms, and the farms grew larger, but there were fewer of them.

Now farming became industry, and the owners followed Rome, although they did not know it. They imported slaves, although they did not call them slaves: Chinese, Japanese, Mexicans, Filipinos. They live on rice and beans, the business men said. They don’t need much. They couldn’t know what to do with good wages. Why, look how they live. Why, look what they eat. And if they get funny–deport them.

And all the time the farms grew larger and the owners fewer. And there were pitifully few farmers on the land any more. And the imported serfs were beaten and frightened and starved until some went home again, and some grew fierce and were killed or driven from the country. And farms grew larger and the owners fewer.
