Actually it is. 40-50 years ago we hit a point where growth stopped absorbing productivity gains. So all future automation also contributes to under employment, lowering the price of labor, reducing the need for further automation.
To try to bring back growth to pre 1970 leavels alone would cause horrific environmental destruction we cannot afford. In addition to taxing the environmental externalities, we also need to shrink the workweek and disburse UBI to the point where labor is in demand again. Only then will future automation work the way we want it to, and the way it did in the past.
