Pyramidal power structures are unsustainable, as has been plainly demonstrated by 100% of them. Given how many of us run our nations on circular power structures (i.e. democracies, republics) and how sustainable and adaptive these models continually prove to be, it is surprising that the commercial world is so slow to adopt these advantages. The urge for control (as a means to a sense of security) is just overwhelming for too many. I suspect this urge is behind the advocacy we see for pyramid power structures, even in the face of insights like those in the article. Maybe that causative factor, and other causes, can be addressed by systematic education. Thanks for this timeless article, HJ.
