From Standard Oil and the Sherman Anti-Trust Act, to the Progressive Era's trust-busters, to the pricing monopoly of Big Pharma and the giant tech companies of today, Amy Klobuchar, in this large, compelling history, writes of the fight against monopolies in America. She begins with the Gilded Age (1870s-1900), when rapacious robber barons such as J. P. Morgan, John Rockefeller, and Cornelius Vanderbilt were reaping vast fortunes as industrialization swept across the American landscape. She discusses the Clayton Act of 1914; the Federal Trade Commission Act of 1914; and the Celler-Kefauver Act of 1950. She explores today's Big Pharma and its price gouging; and tech, television, content, and agriculture communities and how a marketplace with few players, or one in which one company dominates distribution, can hurt consumer prices and stifle innovation.
