Amy Klobuchar, in this large, compelling history, writes of the fight against monopolies in America. She begins with the Gilded Age, when builders of fortunes and rapacious robber barons such as J. P. Morgan, John Rockefeller, and Cornelius Vanderbilt reaped vast fortunes as industrialization swept across the American landscape. She discusses President Theodore Roosevelt, who, during the Progressive Era, “busted” the trusts; 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. Klobuchar is at work on, among others, issues raised by giant tech companies and puts forth her legislative proposals designed to strengthen the antitrust laws and antitrust enforcement.
