Eventually there will be no need for truck drivers, fast food employees, even housekeeping is becoming more and more automated. How will people find work if a machine can always do it better? How will the less-intelligent find work if all the jobs require education they cannot or will not strive for? What happens to them? What happens to their children? How many people around the world are we willing to support without their working? 100 million? 1 billion? Several billion?
This is a serious and terrifying question. Automation is eating jobs so quickly I don't have any idea what the labor landscape will look like in ten years.
What happens to these people? Who lives? Who eats? Who gets medical attention?
Who pays?
