Question: At the same conference, Marshall Sahlins presented a paper entitled, "Notes on the Original Affluent Society", in which he challenged the popular view of hunter-gatherers lives as "solitary, poor, nasty, brutish and short," as Thomas Hobbes had put it in 1651. According to Sahlins, ethnographic data indicated that hunter-gatherers worked far fewer hours and enjoyed more leisure than typical members of industrial society, and they still ate well. Their "affluence" came from the idea that they were satisfied with very little in the material sense. Later, in 1996, Ross Sackett performed two distinct meta-analyses to empirically test Sahlin's view. The first of these studies looked at 102 time-allocation studies, and the second one analyzed 207 energy-expenditure studies. Sackett found that adults in foraging and horticultural societies work, on average, about 6.5 hours a day, where as people in agricultural and industrial societies work on average 8.8 hours a day.
