Social Darwinism and Laissez faire, the ideas of application of Darwin's "survival of the fittest" to human affairs and interaction and the lack of governmental involvement benefitted industrialists or as they were pejoratively termed, Robber Barons. These individuals such as Andrew Carnegie, John Rockefeller, John Pierpont Morgan Cornelius Vanderbilt, etc. amassed great fortunes with little interference from the government. The principles of the Social Darwinism and laissez-faire symbolized the rise of the industrial elite during the Gilded Age (1865-1877)
