"Work time" and "leisure time"
Sahlins' argument partly relies on studies undertaken by McCarthy and McArthur in Arnhem Land, and by Richard Borshay Lee among the !Kung.[5][6] These studies show that hunter-gatherers need only work about fifteen to twenty hours a week in order to survive and may devote the rest of their time to leisure.[4] Lee did not include food preparation time in his study, arguing that "work" should be defined as the time spent gathering enough food for sustenance. When total time spent on food acquisition, processing, and cooking was added together, the estimate per week was 44.5 hours for men and 40.1 hours for women, but Lee added that this is still less than the total hours spent on work and housework in many modern Western households.
The three to five hour work day
Sahlins concludes that the hunter-gatherer only works three to five hours per adult worker each day in food production.[7][8] Using data gathered from various foraging societies and quantitative surveys done among the Arnhem Landers of Australia and quantitative materials cataloged by Richard Lee on the Dobe Bushmen of the Kalahari, Sahlins argues that hunter-gatherer tribes are able to meet their needs through working roughly 15-20 hours per week or less.
