The cause of the historical development in the excerpt is the exploitation of Italian immigrant laborers by contractors. These contractors controlled the work contracts and paid the workers less than they deserved. This created a system where laborers were often in debt and had little power to protect themselves because laws favored the contractors. The point of view in the excerpt is sympathetic toward the Italian laborers. The speaker highlights the unfair treatment and the greed of contractors, showing concern for the workers who suffer under these harsh conditions. This situation is significant for understanding immigration during the Gilded Age because it shows how many immigrants faced economic abuse and difficult working conditions. This mistreatment affected how immigrants lived and worked, shaping the broader historical debate about labor rights and immigration policies. It reflects the struggles immigrants endured while trying to improve their lives in America. Overall, the excerpt reveals the harsh realities behind the Gilded Age's economic growth and immigration patterns.
