This article in System Dynamics Review advocates requiring more vacation time as a tool to decelerate growth in humanity’s ecological footprint. The idea is logical enough, but politically very hard if you ask me. The only way it might be politically possible is in the wake of a crisis, like a famine or sudden shift in climate, that is big enough to be a major wakeup call to the rich countries but small enough that it doesn’t kill a big fraction of humanity (which would decrease our ecological footprint footprint of course, but at an obviously horrible cost.)

As envisioned by Keynes in Economic Possibilities for our Grandchildren, reducing work hours could make sense if it is done in parallel with productivity and wealth increases, and policies that address a fair distribution of the new wealth created by those productivity increases. This brings us back to trying to steer economic and technological growth in a more sustainable direction, trying to at least postpone and limit the next crisis, but having some ideas on how we might take advantage of the next crisis when it happens, while hoping it is not the one that wipes us out.
