The Rise and Fall of American Growth

In 1870, the typical American home was an isolated island of intense labor. The average household was completely disconnected from public utilities; every drop of water for cooking, cleaning, and bathing had to be hauled in by hand, and all waste had to be hauled out. The only sources of light were the candle and the kerosene lamp, meaning darkness dictated the rhythm of life. A full day's work for one person might yield a single article of clothing, and communication with the outside world moved at the speed of a horse. This was the world of our great-great-grandparents.

By 1970, that world had vanished. In the span of a single century, a torrent of foundational innovations had completely rewired daily existence. Homes were now nodes in vast networks of electricity, clean water, sewer systems, natural gas, and telephone lines. The internal combustion engine had replaced the horse, and air travel had shrunk the continent. The drudgery of the 19th-century home was automated away by washing machines, refrigerators, and vacuum cleaners. The change was total. Yet, if you were to transport a person from 1970 to today, they would find life remarkably familiar. The car, the airplane, the kitchen appliances—all are more efficient, but their core function remains unchanged. The primary revolution has been confined to the realm of communication and entertainment.

This dramatic deceleration in life-altering progress is a statistical reality that forms the bedrock of Robert J. Gordon's landmark study. As a distinguished professor of economics at Northwestern University, Gordon dedicated decades to quantifying the economic impact of innovation. He meticulously tracked productivity data and realized that the explosive growth experienced between 1870 and 1970 was a unique, one-time event, an anomaly in human history. He wrote this book to provide a sobering, data-driven counter-narrative to the prevailing optimism, arguing that the economic headwinds we now face are a return to the historical norm, not a temporary slump.

Module 1: The Special Century: A Revolution in Everything

We're moving into our first module, which explores the most transformative period in human history. Gordon calls it the "Special Century," running from 1870 to 1970. The progress during this era was a complete, one-time-only revolution in the human condition.

Life in 1870 was brutal. Most Americans lived in rural isolation. Homes were dark, lit by dim kerosene lamps. There was no running water. Women hauled tons of water and wood into the house each year. Waste was thrown into cesspools or outdoor privies. Infant mortality was staggeringly high. A newborn's life expectancy was just 45 years. Then came a cluster of what Gordon calls the "Great Inventions." They were foundational technologies that rewired society.

The first major insight is that the greatest leap in living standards came from networking the American home. This was a physical network. Electricity was the first layer. It brought clean, bright, and safe light, ending the tyranny of the daily cycle of sunup to sundown. It powered motors that drove a wave of labor-saving appliances. Next came running water and sewer systems. This single development was arguably the most important health innovation in history. It eliminated the drudgery of hauling water and dramatically cut death rates from waterborne diseases like typhoid and cholera. By 1940, the urban American home was a networked hub. It was connected to electricity, gas, telephone, water, and sewer lines. This transformation was a singular event. You can only go from an outhouse to an indoor toilet once.

Building on that idea, the second industrial revolution conquered the tyranny of distance and isolation. Before 1870, life was intensely local. The primary mode of personal transport was the horse. A horse could travel a few miles an hour and required immense resources. The internal combustion engine changed everything. Automobile ownership exploded from virtually zero in 1900 to nearly one car per household by 1929. For the first time, rural families could easily travel to town. They could access better markets, schools, and medical care. In cities, electric streetcars and subways allowed people to live farther from their jobs, creating the first suburbs. This revolution in mobility fundamentally reshaped social and economic geography.

Finally, Gordon's analysis shows that the most significant gains in human health were achieved before the rise of modern medicine. We often credit today's long lifespans to advanced medical treatments. But the data tells a different story. The rate of improvement in life expectancy was twice as fast in the first half of the 20th century as in the second. Why? Public health infrastructure. Clean water, urban sanitation, and food safety regulations did more to defeat infectious diseases than doctors and hospitals did. The 1906 Pure Food and Drug Act, for instance, was a direct response to a public outcry over contaminated meat and milk. These environmental changes, not miracle drugs, were the primary drivers that lifted life expectancy and slashed infant mortality. This period represents the picking of the low-hanging fruit of human welfare.
