We have the economy to get the maximum output for the minimum input
Having 100 people working doing something that could be automated is bad for mankind. It's a total waste. Might as well have them digging a hole then filling it back in.
The problem is that we don't allow for changing work requirements, both on an individual basis with retraining into jobs of equivalent satisfaction and compensation, but also into keeping areas which lose their industry relevant. This causes people to blame the automation.
It's nothing new, in the past workers who felt their livelihood threatened by automation flung their wooden shoes, called 'sabots', into the machines to stop them. ...Hence the word 'sabotage'.
