Jeremy Grantham's latest quarterly letter is out, in which he discusses, as
the title suggests, the road to zero US growth. From
the punchline:
With a little luck, U.S. GDP growth (even after an increasing squeeze from rising resource costs and environmental damage) should remain modestly positive, even out to 2030 and 2050, in the range of 1% at the high down to a few basis points at worst. Increasingly, the growth will be qualitative. Qualitatively, growth is likely to be limited to services as manufactured goods will bear the brunt of the rising input costs. It would certainly help a lot if considerable changes were made in how GDP is measured. It needs to be closer to what we all apparently think it is already: a reasonable measure of the utility of useful goods and services.
The key issue will be how much unnecessary pain we inflict on ourselves by defending the status quo, mainly by denying the unpleasant parts of the puzzle and moving very slowly to address real problems.
This, unfortunately, is our current mode. We need to move aggressively with capital – while we still have it – and brain power to completely re-tool energy, farming, and resource efficiency. We need to do all of this to buy time for our global population to gracefully decline. It can certainly be done.
Summary:
·
The U.S. GDP growth rate that we have become
accustomed to for over a hundred years – in excess of 3% a year – is not just
hiding behind temporary setbacks. It is gone forever. Yet most business people
(and the Fed) assume that economic growth will recover to its old rates.
·
Going forward, GDP growth (conventionally measured)
for the U.S. is likely to be about only 1.4% a year, and adjusted growth about
0.9%.
