Just imagine if economic growth wasn't a natural thing.
What if the extraordinary growth seen throughout the developed and developing world since 1700 ended around the turn of the century?
What if the long term growth assumption of around 2-3% per annum ad infinitum was actually wrong?
How would that change our view of our economy, our social development and our political outlooks?
That's the debate sparked in the last month internationally by a stunning academic paper from respected US economist Robert J Gordon titled: "Is US Economic Growth Over: Faltering Innovation Confronts The 6 Headwinds".
If proven, the implications of his thesis are profoundly sobering.
Gordon argues there was very little real economic growth per capita before 1700. Since then three eras of innovation have powered amazing growth.
The first era from 1750 to 1830 included the invention of steam and railroads. The second era from 1870 to 1900 was the most productive, including the invention of the internal combustion engine, chemicals, petroleum, plumbing and communications. The third era after 1960 saw the creation of computers, mobile phones and the Internet.
Gordon argues the second era created the most growth, while the third era's boost to growth was relatively short-lived and ended around 2004.

He says growth in developed economies such as the United States may drop to less than half the rate seen since 1870 as innovation battles the six headwinds of demography (an ageing population and a low birthrate), a plateau in education, rising wealth inequality, globalisation, energy/environment (global warming) and debt overhangs.
Gordon's conclusion? "A provocative 'exercise in subtraction' suggests that future growth in consumption per capita for the bottom 99 percent of the income distribution could fall below 0.5% per year for an extended period of decades."
If the developed world's growth rate falls to that level for decades to come politicians and voters would have to change all sorts of assumptions, including how much debt can be loaded on to future voters, how to distribute income and how to invest in infrastructure.
Governments of both colours have assumed 'natural' growth of around around 3% per capita over the long run. That has cured all manner of ills. Taking on debt makes sense when income growth in future can be used to pay for it. Running a pay-as-you-go pension and healthcare system makes sense when economic growth in future can be used to 'overcome' the effects of an ageing population.
Widening disparities in wealth and income between the lower/middle 90% and the top 10% can be assumed away when there's enough of a 'tide' of future economic growth to lift everyone's boat.
Removing that assumption about 3% growth changes everything.
Politicians and voters have been saying for years now that innovation will solve the problems. 'Someone' will discover a cheap new energy source or invent a new version of the Internet to make everyone richer.
Unfortunately, that hasn't happened for 40 years, in part because investment in new science has lagged the explosive growth around the turn of the 20th century.
Do we wait and hope for a growth miracle or cut our cloth to the new normal?
