How did industrialization increase the role of the national government?

Industrialization increased the role of the national government by necessitating regulation and oversight of emerging industries and labor practices, which often operated with little regard for worker safety or environmental impact. The government expanded its regulatory framework to address issues like child labor, workplace safety, and monopolistic practices, leading to the establishment of agencies and labor laws. Additionally, infrastructure developments, such as railroads and telegraphs, required federal investment and coordination, further solidifying the government's role in economic affairs. This shift marked a significant transition from a more laissez-faire approach to a more interventionist stance in the economy.
