Hiltzik writes about the largest, wealthiest, and most powerful corporations in US financial history, the railroad companies from the 1860s to the 1920s. While the historical debate has been about whether the owners were “captains of industry” or ”robber barons”, Hiltzik makes it clear these were robber barons. He writes about the following railroad men: Cornelius and William Vanderbilt, J. P. Morgan, Jay Cooke, Edward Harriman, Jay Gould, Jim Fisk, Daniel Drew, Jacob Schiff, George Pullman, Henry Villard, James Hill, Wellborn Fish, and James Hill. Later in this history President Theodore Roosevelt enters as the “trust buster” and arch rival of former associates from New York. The railroad industry was the backbone of the growth and development of the United States and it’s economy. The stock market went up and down with the ups and downs of the railroads. However, the American people began to see the railroad robber barons as too powerful with economic power concentrated by various monopolistic practices such as; stock watering, pools, trusts, and holding companies. Always designed to stifle competition and increase profits. This of course led to increased government actions first by states then by Congress and the Supreme Court. Laws passed in response to monopolistic practices included the establishment of the Interstate Commerce Commission and the Sherman Anti-trust Act. President T. Roosevelt said, “more supervision of business enterprises” was needed. This eventually led to the breakup of several monopolistic institutions by the Supreme Court. Hiltzik concluded that “ American capitalism and its railroads were born together, reached adolescence together, and attained maturity together.” In this maturity they also showed the flaws of unchecked capitalism. A good read in this economic history of the American railroad business.
