OK, let it be not outsourcing to places with lower cost of labor, but to machines. There are whole factories that are operated by half-dozen people who mostly oversee its interaction with other human-run systems, such as trucks.

It will still keep most population away from industrial production. Same thing happened is agriculture a century ago, when machines made 90% of agricultural workers redundant, and huge farms are run by half-dozen people.

(Wait until AI will make a ton of service workers redundant.)
