"I got orders wherever there’s a family not moved out – if I have an accident – you know, get too close and cave the house in a little – well, I might get a couple of dollars. And my youngest kid never had no shoes yet."
– John Steinbeck
The Grapes of Wrath, Chapter 5. The tractor driver demonstrates his greed for a few extra bucks and his betrayal of his own people here. For a few dollars he is willing to do the dirty work of his bank employers and "accidentally" cave in a local tenant farmer’s house with the tractor. This shows how much he has been corrupted by the system, showing no humanity and thinking only of his own self-interest.
