Lots to think about and react to here, but I just wanted to pick up one point:
about how the energy pie is divided up, [...] genuine concern for fairness has to be as much or more about lowering the wealthy than lifting the poor.
At the very extreme of things there is this idea of the "billionaire bunker". Like people can somehow cordon off climate change and energy collapse and all of these destructive forces, IF they have enough MONEY.
I question this. I suspect that many of these ideas take for granted many assumptions about collapse being somehow containable.
Like, are oil wells, tankers, electrical grids and refineries and distribution systems all going to keep running so that the rich can live life as usual while everything else goes to ruin? We will still have a system?
But what if you make a department of Honey Bun Efficiency? There is surely a simple solution for your fiscal crisis.
