No one who can continue to work will be permitted to settle into a passive income from government. The rub, of course, is that the aging around the world must continue to align their skills with what's in demand in the workplace. Obviously, government will have to provide free or low-cost training to the workforce.
The Guardian explains this as only one of the ways in which work is changing.
Other disruptions include automation of both blue and white collar jobs. The latter are no exception. IBM's Watson already does medical diagnoses. You bet, all generations will be chasing retraining for what still requires a human.
Also, the on-demand-economy will continue to expand. Anyone who has been on Upwork looking for assignments understands how competitive it is to land freelance work. Because bidding is global those with routine skills will experience wage deflation. After all, the plain-vanilla U.S. web designer has to factor in what the colleague in the Philippines is requesting for compensation.
Another reality is employer monitoring. Technology allows them to track more and more kinds of employee activities. The expectation about personal privacy will be blown into a million pieces.
In all this, the good news is that the powers-that-be want us to remain in the workforce. Therefore, we can anticipate government-generated policies which facilitate that.
