What Will Happen to the "Bottom Half?"

Predictions vary as to the percent of jobs that will be lost to automation, offshoring, and gigging but it’s likely to be between 20 and 60 percent within the next decade or two. 

Consensus is that much of the remaining decent-paying employment will demand ever more brainpower, technical chops, and communication skills. And with so many applicants available, employers will be able to insist also on people who are likeable, reliable, enthusiastic and healthy.

The Big Question is, what’s going to happen to the many millions of people who don’t get hired for those jobs? I fear that things will be different from previous technological waves in which new technologies, net, created more new jobs. I predict that because so much of the future economy will be based on digital products and services, which can be produced by the millions with a push of a button.
