Eighty-five per cent of the almost 6 million American manufacturing jobs that disappeared between 2000 and 2010 did not go anywhere; they just evaporated. The workers were replaced by tireless machines that could do their jobs more cheaply.
Although Kerry did not mention it, the same thing is now happening in China: relatively cheap Chinese labour is still more expensive than the automation that replaces it. Even in India, where wages are lower still, there is talk of "premature deindustrialisation".
It's a misleading phrase, because it suggests India will never become fully industrialised. It probably will -- but perhaps without creating a huge industrial working class with reasonably good and steady wages. Further industrial growth is likely to come mainly through automation, and employment in manufacturing may be peaking right now.
So Donald Trump is barking up the wrong tree, as are the other populists emerging all across Europe, and their emulators in the developing world. Why do they all persist in blaming free trade and globalisation instead of automation? Because you can't do anything about automation.
If you are a politician, it's better to blame globalisation because you can do something about that. You can build walls, impose tariffs, make all sorts of impressive gestures to stop the free trade that is allegedly destroying the good jobs. Or more precisely, you can win political power by claiming that you will do those things and thereby solve the problem.
Whereas nobody will believe you if you say automation is what is really changing the economy, and so you are going to stop the automation. That's Luddism, and everybody (or at least, everybody at Davos) knows that doesn't work. So the rich and the powerful are way out ahead of the pack in accepting that growing automation really is going to destroy large numbers of jobs.
A recent Citibank research note forecasts that automation will eliminate 57 per cent of all existing jobs in the developed countries within the next 20 years. In China, 77 per cent of manufacturing jobs are at risk over the same period. And the notion that the economy will create other, better jobs to replace them is just a comforting myth. Most of the new jobs being created are MacJobs.
If more than half the workforce ends up unemployed -- and therefore humiliated and broke -- their anger will be so great it could sweep away the comfortable world of the ultra-rich. Which is why there are sessions at Davos this year considering radical ideas like a "Universal Basic Income".
To stop the populism, first you have to deal with the anger.
