longer - sorry
Well - let me say sorry up front - the following is going to get quite long...
@Mav 23:
Hehe - if I knew the definitife answer to that question I'd probably be elected world president
More seriously. What to aim for:
* Maximise personal rights, especially privacy.
That one should be a natural, but very hard to do - "who watches the watchmen"...
No censoring. No SPAM.
* Minimise poorness around the globe.
All equal - all glad or something like that Communist propaganda. It is a fact however that almost all wars have their roots in this monetary differences. As long as the West partially lives at the cost of for example Africa there always will be war and terrorism. Pay so they don't attack us? You can call it blackmail or you can call it a sain decision. It is unavoidable to ensure a united world however IMHO.
* Take care for the world.
Take care for other humans. Accept their believes. Be tolerant. Treat others like you'd like to be treatened by them.
Take care for animals. They feel pain just as much as a human does. And they as well deserve rights to have a pleasurable life. Well I'd be happy if we'd all turn Vegetarian, but that is a different story.
It is not a good idea however to maximise profits (yeah - here it is again - money, the root of most evil) by using for example growth hormones at the cost of the animals, at the cost of our personal health because of the sideffects of the meat and finally at the cost of having to actually destroy the overproduction.
Also note that pleople that like to torture animals also got a lower threshold for being nasty with humans. Teach the respect at the lowest possible point.
Take care for our environment. There are many resoures we waste every day that we cannot restock - oil as the most prominent example.
It is an insanity if a country like the USA needs more electricity in summer for cooling the in winter for heating, especially when the heat is mostly human caused (CO2, hole in the Ozone layer).
So many stuff could be easily solved. Why not try solar energy for cooling? After all there is sun when it is hot, isn't it? Also there is a big possibility to reduce traffic, especially the trucks. Is it a necessarity if potatoes are driven from Germany to Italy to get washed?! Also traffic could be switched to less polluting transport methods. Let me give you a vision: Why not use solar enpowered drone like flying machines (planes, baloon, zeppelin) whatever. Sure they would most likely be slower - so who cares?! What goods are really time important?
* Reduce the political influence of multi national corps.
Very un USish, isn't it? But without this clause neither point 1 nor point 2 nor point 3 would hold for longer.
DRM, DECSS Lawsuit, ...
@Ridgerunner: You are wrong in your arguments IMO. Yes - Bill Gates might be responsible for a lot of jobs. You ignore something however. How many jobs have been lost by the destruction of countless companies by MS? It is a fact that many small companies create more wealth for all then one big one. Also how much money was lost for the customers because a quasi monopoly forced them to pay insane prices (Office for example), but also Win2000 Pro...
* Then lets get to a government. Hmm yes - we'll need one I am afraid. Someone has to watch over the rules I fear.
I'd tend to go somewhere into the direction of a technocracy here. I am sick and tired of politicians that don't have a clue about what they are talking about. Let the most knowing people people for a job also get the job. Also by this reign of intelligence you reduce the risk of dependancy on some interest groups.
Elections or votes (they don't change much anyhow - do they? *sigh*) could be skipped easily as long as it is made sure that the rulers follow the wishes of the majority. Again something a scientist will more likely do then a politician.
Ok, now let me further plot my utopia:
Well weapons (of mass destruction, but eventually even guns) will be unnecessary. There won't be any tensions left after a while. Crime will also (almost?) vanish - it will be unprofitable.
Also we would not need a defense against aliens. Every race that evolved far enough as to reach us and hasn't self destructed on the way to get that advanced is very very very likely to have extremely hight ethical values.
Well I think that are ('in short') the most important points. I could go on for several more pages, but I assume you get my point by now.
