How did the interstate act help regulate big business?

The Interstate Commerce Act of 1887 aimed to regulate the railroad industry and curb monopolistic practices by establishing the Interstate Commerce Commission (ICC). This act required railroads to publish their rates and prohibited discriminatory practices, ensuring fair pricing for all customers. By regulating interstate commerce, the act sought to promote competition and prevent unfair practices that could arise from unchecked corporate power, thus helping to protect consumers and smaller businesses. Overall, it marked a significant step toward federal regulation of big business in the United States.
