L’indépensé : le travail de demain

It seems that a new category of thinking is about to come about: that of avoided costs which could now be counted and which we could call "unspent" (indépensé)
That being the case, how can integrate this new way of thinking, which would be that of "preferring not to", which paradoxically would lead to an increase in value. This new way of thinking could be applied to fields such as design (including ergonomics), the economy, politics, services, etc.
