The elephant curve (named for it's shape) tells us that globalization (the free movement of people and capital around the world) over the last 35 years has helped lift massive numbers of poorer people into the middle classes in the developing world (especially China), and helped the one percent disproportionately in developed economies. During these years, middle class incomes in the developed countries have grown much less (perhaps 1% per year).
November's jobs report noted 174,000 new jobs created in the US. Despite this and our President elect's promises to "bring the jobs back", there's a real possibility that in the near future, self-driving cars, buses and trucks may put millions of people out of work. Drones, robotics, and automation of every kind may reduce the number of jobs permanently.
As Erik Brynjolfsson, a professor at the M.I.T. Sloan School of Management, told MIT Technology Review, “Productivity is at record levels, innovation has never been faster, and yet at the same time, we have a falling median income and we have fewer jobs. People are falling behind because technology is advancing so fast and our skills and organizations aren’t keeping up.” It is, he said, “the great paradox of our era.” Quoted here.
$7,000,000 in tax credits and billions in defense spending convinced Carrier not to move a few hundred jobs to Mexico. There will probably be lots of construction and related jobs created to rebuild our country's infrastructure. But jobs that are automated away by technology aren't coming back.
