Sure, society survived, but the decades after the industrial revolution/jobs realignment were wracked by insurgency, terrorism, the rise of the communist, fascist and anarchist movements, and culminated in two ridiculously destructive wars and a catastrophic depression. I'm not saying those things will happen now too (we would never see extremist violence in this day and age, would we?) but given that history tells us that when large numbers of young-middle aged men are underemployed, you get violence, crime, and deaths of despair, perhaps we would be wise to spend some time thinking through how to help those people reestablish their connections to society.
