Final answer:
Hunter-gatherer societies have the least social stratification due to their egalitarian nature and limited opportunity for wealth accumulation.
Step-by-step explanation:
The question asks which type of productive technology in a society leads to the least amount of social stratification. Comparing different societies based on their productive technologies and levels of stratification, it is evident that hunter-gatherer societies have the least social stratification. These societies are characterized by a reliance on the environment for sustenance through hunting wild animals and gathering plants. They tend to be nomadic, moving to new areas when resources become scarce, and are generally egalitarian because the mode of subsistence does not allow for the accumulation of wealth or surplus. In contrast, industrial and postindustrial societies, which utilize technology to control their environment, have greater social stratification due to factors such as wealth accumulation, specialized occupations, and the control of resources.
In terms of social stratification, a society with hunting and gathering as its productive technology has the least amount of social stratification. In hunter-gatherer societies, everyone typically has equal access to resources and there is a greater sense of egalitarianism.
On the other hand, in societies with industrial or postindustrial productive technologies, there tends to be more social stratification. These societies are characterized by specialized occupations, surplus production, and a hierarchical structure where some individuals have more wealth and power than others.
