In Marshall Sahlins's Stone Age Economics, he studies work time of hunter gatherer tribes in Africa, Papua New Guinea, the Amazon etc. They often less work less than 40 hours a week. The hunter gatherer painting in caves in Chauvet seemed to have leisure time. Less hours than some fresh college grad pounding out C++ or C# for Electronic Arts any how.
The past 50 years has seen the hourly wage stay flat while the profit workers create is sucked up by the heirs.
Paying for four years if college to get a CS degree, then studying Leetcode, interning, working cheap as an associate/junior used to be seen as a good path, but obviously since late 2022 this has stagnated for most.
