Finally, nothing in evolutionary biology teaches us that human beings ought to work. Studied hunter-gatherer societies are as multi-faceted as agrarian and technologically driven ones, but they all seem to share a 20 hour work week and a strong affinity for story telling and art.
Honestly, if you followed evolutionary biology we all should be working quite a bit less and producing way more art. The idea that people will fall into dissipation without work is supported by very little science, and certainly no biological science.
Human beings need missions, not labor, to be fulfilled. The market economy seems capable of only supporting a very narrow slice of mission oriented work, the rest does seem like drudgery to me.
