Let's say GP was right and 1M jobs disappeared. Robots are cheaper. Are cars going to get cheaper? My bet is on no. Where does that money go? Up. Who will buy the cars? Definitely not the 1M people losing those jobs.
I'm not saying we should go backwards, but just producing more stuff cheaper with less labor without a goal in sight isn't a net positive impact on the world, and the economic inequality will only grow steeper.
I'm saying this as a cushy white collar business owner that will likely be comfortably ahead of that curve. But we're still just lemmings scurrying to get ahead of everyone else, while a whole lot will be left behind.
This is what decided this election, regardless of anyones politics (I certainly didn't agree with the choice).
