A book review of The Rise and Decline of Nations: Economic Growth, Stagflation, and Social Rigidities, by Mancur Olson.
Olson showed back in 1982 that modern macroeconomic theory was basically worthless in developed stable countries. Macroeconomics posits a free market in which wages and prices adjust dynamically. That applies to an ever-smaller sector of the U.S. economy. We have a rapidly growing governnment that directly or indirectly employs more than one third of our workers, many of whom are unionized. We have a health care system that consumes 16 percent of GDP and is staffed with doctors who restrict entry into the profession via their licensing cartel. The financial services sector is about 10 percent of the economy and they now tap into taxpayer money to keep their bonuses flowing in bad times. The automotive industry kept itself profitable over the years by successfully lobbying for import tariffs. When the profits turned to losses, they successfully lobbied to have taxpayers pick up those losses. A university-trained macroeconomist might be able to predict what will happen to babysitters in a depression, but not the price of cereal, the wage of a manufacturing worker, or the fate of those Americans who collect most of our national income (e.g., Wall Street, medical doctors, government workers).
