So much for unbounded progress

Paul Krugman reviewing The Rise and Fall of American Growth: The U.S. Standard of Living Since the Civil War:
Robert J. Gordon, a distinguished macro­economist and economic historian at Northwestern, has been arguing for a long time against the techno-optimism that saturates our culture, with its constant assertion that we’re in the midst of revolutionary change. Starting at the height of the dot-com frenzy, he has repeatedly called for perspective: Developments in information and communication technology, he has insisted, just don’t measure up to past achievements. Specifically, he has argued that the I.T. revolution is less important than any one of the five Great Inventions that powered economic growth from 1870 to 1970: electricity, urban sanitation, chemicals and pharmaceuticals, the internal combustion engine and modern communication.

In “The Rise and Fall of American Growth,” Gordon doubles down on that theme, declaring that the kind of rapid economic growth we still consider our due, and expect to continue forever, was in fact a one-time-only event. First came the Great Inventions, almost all dating from the late 19th century. Then came refinement and exploitation of those inventions — a process that took time, and exerted its peak effect on economic growth between 1920 and 1970. Everything since has at best been a faint echo of that great wave, and Gordon doesn’t expect us ever to see anything similar.

Is he right? My answer is a definite maybe. But whether or not you end up agreeing with Gordon’s thesis, this is a book well worth reading — a magisterial combination of deep technological history, vivid portraits of daily life over the past six generations and careful economic analysis. Non-economists may find some of the charts and tables heavy going, but Gordon never loses sight of the real people and real lives behind those charts. This book will challenge your views about the future; it will definitely transform how you see the past. [...] 
As he says, “Except in the rural South, daily life for every American changed beyond recognition between 1870 and 1940.” Electric lights replaced candles and whale oil, flush toilets replaced outhouses, cars and electric trains replaced horses. (In the 1880s, parts of New York’s financial district were seven feet deep in manure.)
And the future?
So what does this say about the future? Gordon suggests that the future is all too likely to be marked by stagnant living standards for most Americans, because the effects of slowing technological progress will be reinforced by a set of “headwinds”: rising inequality, a plateau in education levels, an aging population and more.
