Yes, but additional production is always produced via credit. A system without credit/debt does not need to grow and therefore it doesn't grow. Rain forest people are not forced to increase their 'output'. Their output does not grow in thousand years. Only nationalized people are forced to produce surplus, because they are forced to pay tribute. That's the root of credit/debt: organized violence (collectivism/society).
I am sorry but that's some weird, utterly false statements.
If I am owner of my production I will produce beyond my consumption needs (that's called capital accumulation) to improve my standard of living in the future, even if I have no debt. The capital accumulation will enhance my productivity and thus allow me to produce more output.
The output of rain forest people doesn't grow because their culture haven't evolved private property rules, it is no related to debt.
Tribal people don't have private property rules because they don't want it and because they don't need it. They live within an egalitarian
community. Private property rules are always guaranteed by organized violence of the state mafia. It is a thing of the
society, which is collectivism, which is the perversion of the community .
Cultural rules don't come from conscious choice.
Tribal societies aren't egalitarian. Human beings are hierarchical no matter where you look.
Violence exist among tribal societies, they are more violent than modern occidental societies.
