hmm. Difficult to answer for me

as my dreams should stay dreams, if they would get real I'd have nothing to dream about.
But what I'd would like to see in the world is a mixture between communism and democracy, where "fair use" would not be an empty slogan.
Communistic democracy does sound like a contradiction, but it really isn't.
Just think we could do without Bush, Merkel or Putin and vote directly about each issue. The basic setup is allready there, just use the internet
And "fair use"... imagine the music industry would no longer exist and recording/sharing a song would not be harder punished than child-abuse.
Imho those 2 point would free up enormous amounts of money (not only in terms of politicians salaries, bribes or lobbying-money) which could be viable used on other fields (e.g. social ones)
