Basically, those that are more "brainy" need a higher level of mental stimulation in order to not be bored. Being given too much mental stimulation relative to your intelligence/skills results in anxiety. The sweet spot is somewhere in between and we seek this sweet spot (or at least stumble upon it and remain sticky to it). People then sort themselves over time into these buckets s/t (generally), the brainy people end up doing brainy things, and the not-so-brainy people do less-brainy things. Reversing of roles would be mutually detrimental to both parties. |
The difference is that the rock-digging is primarily for myself and my family, rather than for shareholders. Would "brainy" people need a higher level of mental stimulation if they were doing road-building work on their own street? I certainly wouldn't be happy as a truck driver, but I could easily work as a truck driver for a month straight if the reward was significant time off that I could spend with my family and friends.
I'm not doing a great job at explaining this- a lot of people have been trained to believe in the necessary division of labor, but their belief that they could never do manual labor allows the overlords of society to keep everyone in the rat race. If you think you could never work in a textile factory because you need more mental stimulation than that, then you won't ever consider a vision of society where you help produce textiles.
If people really want a ten-hour work week, we need to be building everything that we use in our society for ourselves, not relying on serfs in foreign countries to do the grunt work while we do "stimulating work", i.e. building elaborate processes for white collar companies providing services that we don't actually need.
