America was not just discovered, it was built. Everything around us has been an outcome of the country's past. At the end of the Civil War, America was a country that was on a border of failing; with a declining democracy and split into two. America rebounded from that unsure time and came to an era where the United States was a great power. This changeover was the cause of a new generation of business-savvy, innovative and determined men and workers. Whether they are called America's Captains of Industry of Robber Barons, they changed America and set new standards for the business world.
