Final answer:
A letter to the editor can be written from the perspective of a muckraker advocating for labor reform or a business owner opposing it.
Step-by-step explanation:
A letter to the editor of a New York City newspaper can be written from the point of view of either a muckraker advocating for labor reform or a business owner opposing it. When discussing the impact of the Industrial Revolution and government regulation, the muckraker can highlight the exploitative working conditions in factories, low wages, and the need for labor reforms such as shorter work hours, safer working conditions, and the abolition of child labor. On the other hand, the business owner can argue that government regulation imposes excessive burdens on businesses, stifles innovation and economic growth, and that labor reforms should be left to voluntary agreements between employers and employees.
