How does Studs Terkel use imagery in Hard Times; an Oral History of the Great Depression?

Imagery:

"They were denied schooling. They were called rednecks and crackers and damn niggers ... It was a protest against things economically unavailable. I interpreted this protest and related it to the Bible—instead of calling them rednecks and hillbillies."

"Their faces, I'd stand and watch their faces, and I'd see that flat, opaque, expressionless look which spelled, for me, human disaster ... They had lost their jobs, lost their homes, lost their families. And worse than anything else, lost belief in themselves. They were destroyed men."
