Faut descendre un moment avant d’avoir la réponse :
One likely reason, says Amy Bogaard, an archaeologist at the University of Oxford who wasn’t involved with the study, was that land was readily available there. Her recent work, some with Kohler since 2017, has shown that using draft animals for plow agriculture typically only increases inequality in societies where land is scarce. In Egypt and Mesopotamia, for example, farming is confined to river valleys. “There’s nothing about the plow that inherently causes land limitation,” Bogaard says.
Bogaard says many of the Carpathian Basin societies appear instead to be what she calls “labor-limited.” In labor-limited societies, commoners upset over a leader who demands too much of their time can simply move elsewhere, as there is plenty of available space. Indeed, Duffy says, people in the Carpathian Basin frequently “voted with their feet” by leaving existing communities and forming new ones.
Du coup, moins de population sur un territoire cultivable donné = plus d’égalité. Ça va dans le sens du malthusianisme :) (de gauche)
Trop de densité de population = exploitation et inégalités, en étant impossible d’en partir.
