This economic transition will eventually effect everyone. Everyone. These people are just at the front end of it.
Also, if you compare the rate of job displacement right now with technology compared to say the early 20th century where a majority of the jobs that existed 50 years prior were "destroyed", then it doesn't seem like we're at much of an inflection point.
More likely, because we have development policies that make it hard/expensive to move, we're not putting people in the new jobs like we used to--this has down the line effects of slowing growth because the workers who are also consumers aren't spending what they could have.
Say that in another thirty years, though. You're referring to billions of people in countries that haven't yet entered a post-industrial economic situation. Are those billions any safer than the millions in the U.S. who've fallen out of it?
