The benefits not happening automatically doesn't mean bloodshed is the solution. I like to think that we could solve the problem with intelligence and design. I forsee that some nation will come up with a better system that does not require everyone to be consuming and employed. Maybe a UBI? Maybe some universal dividend on capital? The savings from having only the best workers employed, combined with the fruits of leisure, will propel that nation ahead and others will struggle to catch on with it.
