The quote from John Steinbeck's "The Grapes of Wrath" reflects the profound struggles and injustices faced by laborers. It indicates that when one purchases goods produced by these individuals, they are not just acquiring physical items but the culmination of hard work and the emotional burden carried by the workers. There is an inherent value in their toil, yet it comes with an acknowledgment of the pain and sorrow that goes unspoken, highlighting the deep personal sacrifices involved in agricultural labor.
