This document discusses the major factors that drove industrialization in America, including influential thinkers and innovators. It describes how Adam Smith's theory of laissez-faire economics and capitalism emerged. Key industrialists like Carnegie, Swift, Vanderbilt, Eastman, Bell, Edison, and Rockefeller revolutionized various industries through technological innovations. Mass factory production required large numbers of immigrant and child laborers who worked long hours in poor conditions for low wages. Unions eventually advocated for better treatment of workers and an eight hour work day. Industrialization transformed America and its impacts are still seen today.
