Check out this article for a good summary of all of the pressures on employment coming from technology and automation. I particularly appreciated Jon Evans' efforts here to connect the dots between the loss of employment with the first wave of efforts to deal with the problem: Basic Income or Negative Income Tax. Some writers have taken a dystopian view of this trend, others a utopian, but Evans suggests that the future has already happened. Only instead of happening in America and other developed countries, he suggests post-work societies exist in Brazil, Russia, and India. Also great is the list of links which is a veritable who's who on this topic. Enjoy!
