Positively brilliant writing. I could pick any number of things to quote, but this one is glaringly important to understand.
Technology-generated income inequality is also a threat to our free market economic system because it reduces consumer demand by reducing the number of consumers, principally workers, with the ability to purchase goods.
The economic concept of creative destruction only works, to the extent it can work, when new jobs are created to replace the old jobs lost due to the new, disruptive technology. And those new jobs must be more-or-less comparable, over the long haul, to the jobs they displace in terms of income & benefits, the numbers of people gainfully employed, and their availability to the displaced workers. Anyone who has been paying even a little attention to the last 2-3 (or more) decades should be able to see that this has not been the case. Usually the only people who care are those directly affected by the job loss. Well, the wolf is at the door now for us, too.
You can't run the world's present economic model by selling stuff to a shrinking pool of people that still have enough disposable income to float the whole enterprise. There will never be enough über-rich to manage it. So much bullshit arguing over capitalism vs. communism vs. socialism / conservatives vs. liberals, etc. The "ism" that would be the logical end to continuing to put more and more people out of work via the miracles of technology is called feudalism. We're working slowly but steadily towards it all the while. Anyone here, besides the would-be lords, barons, dukes, etc. want to give that a go?
