The rapid industrialization of the U.S. economy in the late 19th century has been accredited to big businessmen like Andrew Carnegie, J.P. Morgan, and John D. Rockefeller. While their business practices led to the growth of business and personal fortune, it came at the expense of the laborer, who worked long hours for little pay. Debate the success of these individuals by discussing the positive and negative social, economic, and political impacts of their business practices. Does one side outweigh the other? Would you consider each of them either "Captains of Industry" or "Robber Barons?" You may analyze each person individually or group them together. Make sure to provide examples for each to support your answer. Make sure to support all of your opinions with examples/facts and cite all sources used to develop your answer.
