There's a lot that's wrong with this post, which is at odds with all the available anthropology on hunter-gatherer tribes. For instance, the death by age 30 idea is completely misleading. While it's true that infant-mortality was very high, the life expectancy after childhood was very similar to modern man's. And you can't have it both ways: high infant mortality is just one of the mechanisms by which the biosphere maintains ecological equilibrium. Without it you end up with gross overpopulation, resource depletion, global environmental collapse etc. etc.
Your understanding of freedom is also problematic. Hunter-gatherers had enormous self-responsibility if the wanted to stay alive. They had to work HARD just to survive. Freedom in wilderness circumstances does not mean what it has come to mean in modern society. It implied enormous responsibility. Nowadays, modern man has lost all conception of freedom beyond days off from work so as to fritter away his time in hedonistic pursuits.
