Nothing has been more central to America's self-confidence than the faith that robust economic growth will continue forever. Between 1891 and 2007, the nation achieved a robust 2% annual growth rate of output per person. Unfortunately, the evidence suggests to me that future economic growth will achieve at best half that historic rate. The old rate allowed the American standard of living to double every 35 years; for most people in the future that doubling may take a century or more.
The growth of the past century wasn't built on manna from heaven. It resulted in large part from a remarkable set of inventions between 1875 and 1900. These started with Edison's electric light bulb (1879) and power station (1882), making possible everything from elevator buildings to consumer appliances. Karl Benz invented the first workable internal-combustion engine the same year as Edison's light bulb.
