Structural Unemployment Shift?

Mitch Chao seems to think so:

The root cause of current massive unemployment in this nation is result of rapid transformation of technology landscape and management innovation. The nature and aim of majority technological advance is to enhance efficiency and reduce cost, mostly labor cost.

Anyone fly recently? Did you notice self-check in lane (you make your own boarding pass in advance online) at most airline counters. Anyone shopping in Supermarket lately, did you notice self-checkout line?

What we need is out of box thinkers to explore how to lead a meaningful life without full employment for about a quarter American adults (not necessarily the same people) at any give time from this point forward.

Coincidentally, this echoes my own views from long ago.
