those that take issue with the figures i cited and societies they describe, please listen to the cultural anthropology lecture i linked to in that previous thread.
a large body of evidence exists for the absolute superiority of life in "primitive" societies any which way you look at it (and the more "primitive"/smaller/older you go, the better) , but, understandably, it is always met with total resistance.
(and please, i'm no talking about 18th century or the middle ages. but a bigger perspective of the evolution of human societies)
