When i was 8 years old or so, i read a comic book about The Smurfs (those blue creatures who live in mushrooms).
The story is so fascinating and true,
the title is called De Geldsmurf (= the Money Smurf).
short introduction to the smurfs : The smurfs live in their town in the forrest, and all have their own job. When the farmersmurf wants a bread, he just goes to the bakkery and get's a bread, he don't have to pay, he don't have to give anything in return.. they all live like one big family, sharing every thing. The only "leader" they have is the Great Smurf, who is the oldest and wisest one, it's more like a dad of the family than a real leader.
now the story: Everything goes well in smurfs' town, until the day that one of the smurfs have to go to the Human world. He there meets the phenomona called money, and concludes it would be a good idea to introduce money in smurfs town.
So, he does that, and in the beginning, the smurfs support the idea. But later on, Smurfs begin feeling unhappy, they live in competition with each other, rather than live as a community. Some smurfs, who didn't have a job didn't have anything to eat, etc.
This post is kinda off-topic, but i really had to tell this.
I think all 10-year old kids must read this book, so they can support the utopic idea of a community-based world.
After all, we're not smurfs, maybe every system is doomed to fuck for us, humans. Capitalism surely is, but communism is too, and anarchism also.. It's not the system itself that causes the problems, it's some very small group off people who fuck it for all.
U also talk about a tribal way of life; probably that tribal way wouldn't stand long, as there's cultural evoltion, so it would take some 1000 years till we're at this point of technology again, and say it 's fucked again. And, also, i don't think living in such an ethnic group wold really be fun.. Diseases, famine and deads are very common. They have very cruel rules..
conclusion: the only good system is a sound system
