Why does George say the migrant worker's who travel from farm to farm are the loneliest people in the world?

George describes migrant workers as the loneliest people in the world because they constantly move from place to place, forging no lasting connections or relationships. Their transient lifestyle isolates them, as they lack a stable home and community. This isolation is compounded by the harsh realities of their work, leaving them without companionship or emotional support, which deepens their sense of loneliness. Ultimately, their pursuit of better opportunities often results in a profound sense of alienation.
