This very readable and well-researched book suggests that U.S. industry has become increasingly concentrated over the past several decades. Since the Chicago School convincingly argued in the 1970s that oppressive antitrust regulation prevented economies of scale for corporations and lower prices for consumers, the U.S. government has consistently allowed historic industry consolidation. The authors cite convincing academic evidence and clear examples (e.g. two companies control 90% of the U.S. beer market and four airlines dominate air traffic) of growing monopolistic behavior weighing on the U.S. economy and income inequality. The authors’ solution is a return to authentic capitalism. As an increasing percentage of profits flow to the most dominant companies, the takeaway for investors is clear. Find and invest in those companies that are insulated from extreme competition.
