The US didn't experience its dramatic economic growth in the 1800s by assembling a large and disciplined army; instead, it disassembled large and disciplined slave plantations, moving the agricultural center of the country to smaller, more productive farms in the North. (Farm productivity per acre continued to vary inversely with farm size, worldwide, until the 1970s.) I think it was its network of what we would now consider small industrial companies, coupled with its relatively low level of violence (due to geographic isolation), that enabled it to outstrip many of the Great Powers in economic growth.
By contrast, during the Edo period, Japan was an extremely large and disciplined organization --- which produced some remarkable art but also made it militarily and economically weak.
So I think the picture is much more complex than, "The success of a society was proportionate to its ability to assemble large and disciplined organizations." I suspect Drucker and Coase's insights may help to provide a more nuanced view.
