What factors explained the emergence of larges corporations and what did Americans think of them?

The emergence of large corporations in the late 19th and early 20th centuries was driven by factors such as industrialization, technological advancements, and the expansion of the railroads, which facilitated the growth of markets and economies of scale. Additionally, financial innovations, like the establishment of stock markets and investment banks, allowed corporations to raise capital more easily. Americans had mixed feelings about these corporations; while some admired them for driving economic growth and innovation, others criticized their monopolistic practices and the concentration of wealth and power, leading to calls for regulation and antitrust actions.
