of course we work a lot more because we want some of that economic surplus to reinvest it back into things that we think will improve our life. a relatively constant life wouldn't require that. also our decision-making and surplus distribution system is very very inefficient compared to a few hundred strong community's.
economically we can afford to build millions individual cars and houses and offices, fully furnish them, and do this again-and-again when old buildings get demolished, old stuff gets dumped into landfills.
we can afford to build tanks and bombs and then do that again and again, and to maintain standing armies.
unfortunately efficiency and longevity is just not a global concern :(
Always easier to have a good life with extra help from the government :)
Suggests they don't really have it all figured out though. Being able to defend yourself from invaders is an important thing to figure out, too.
