Huh, yeah. I just read the article and they don’t seem to address individuals with large networks not dying and passing that on. There is a stated assumption that per capital wear will increase over time, but that seems overly simplistic.

So in short, yes, wealth horders do seem to be an issue not addressed.

I did fail to catch how much of the observed inequality was accounted for with the model. Perhaps that is in a more detailed paper.
