The song "Pastures of Plenty" by Jefferson Starship is a tribute to the migrant workers who came to California during the Dust Bowl era in the 1930s. The lyrics describe the hardships and struggles of these workers as they traveled westward to find work in the orchards and fields of California, Arizona, and Oregon. The narrator of the song speaks of the difficult work he has done, from hoeing fields and traveling dusty roads to sleeping on the ground under the moon. He talks about the various crops he has harvested, from peaches and prunes to beets and grapes. He also mentions the Grand Coulee Dam, which provided water to irrigate the dry desert ground. The song celebrates the resilience and perseverance of these migrant workers, who have traveled all over the United States in search of work. Despite facing discrimination and hardship, they continue to fight for their rights and for a better life for themselves and their families. Overall, "Pastures of Plenty" is a powerful tribute to the migrant workers who helped build America's agricultural industry and whose contributions often go unrecognized.
