The Rise and Fall of American Growth

1. The 1870-1970 century was a one-time event. Gordon's central thesis is that American living standards rose by an order of magnitude in those hundred years because of a unique cluster of inventions that can only be invented once. Electricity, the internal combustion engine, indoor plumbing, clean water, telecommunications, and mass production were each transformations of daily life, not incremental upgrades. 2. GDP statistics undercount this revolution. The book argues that conventional measures miss the change because they cannot price what was previously unavailable at any price. Eliminating infant mortality, replacing horse manure with clean streets, lighting a home after sunset, were welfare gains that nominal output figures barely register. 3. The pace before 1870 and after 1970 was much slower. Pre-industrial life changed little over centuries, and post-1970 productivity growth has lagged far behind the great century. Gordon uses long-run total factor productivity data to show that the middle century is an outlier, not the baseline. 4. The digital revolution is real but narrower. He concedes that information technology has transformed entertainment, communication, and some business processes, but argues these gains are concentrated in a few sectors and are smaller in welfare terms than the bundle of last-century inventions. Faster email is not running water. 5. Productivity since 2004 has slowed sharply. The book documents that despite smartphones, broadband, and cloud computing, U.S. labor productivity growth has decelerated. Gordon treats this slowdown as evidence that the easy wins have already been harvested. 6. Four headwinds make future growth harder. Rising inequality, stagnating educational attainment, an aging population, and accumulating government debt each subtract from per-capita living-standard growth going forward. Even strong invention may not translate into broad-based gains in median income. 7. Growth is not destiny. Gordon resists the framing that progress is automatic. The great century happened because of a specific combination of inventions, immigration, education, and institutions, and there is no law guaranteeing a similar combination in the next. 8. Policy can soften the slowdown but probably not reverse it. He suggests investing in education, reforming taxes, and improving immigration policy to lift the floor, while warning against magical thinking about a Second Machine Age. The book's tone is empirical and sober: the future will likely grow more slowly than the past most living Americans remember.
