Richard D I'm awaiting with baited breath though which other current democratic systems you would consider superior to the German one though, and *precisely* why (cough *electoral college* cough).
One point: an electoral college system is a *fantastic* approach to a government of a *large* nation composed of a number of independent-minded semi-sovereign states. A "United States of Europe" or a "United Federation of Planets" would do well to have something like this, and like the US's split Senate/House approach, where it's partially based on population ratios, and partially based on set political regions.
For itty-bitty countries like, say, Belgium, it doesn't make a whole lot of sense. But if you tried to turn the EU into a single nation... the smaller countries like Belgium would be simply steamrolled by the likes of Germany. Without *disproportionate* controls, German interests would dominate the new nation. And the smaller nations would quickly come to regret having been involved in that mess.
How to return this discussion to relevance? Hmmm. Assume an alien invasion of, say, the EU. Aliens move in in large numbers and start voting for things to be made *their* way. Soon enough, the lands of the EU would no longer resemble what they were that inspire the Zeta Reticulans to move there in the first place, but would become chaotic versions of Zeta Reticuli. The indigenous population would become like aliens in their own lands...
Nah, that's crazy. The EU would never allow such obvious insanity.
