The best solution is to have a limited government, so that even if the elitists or masses decide to vote, they're limited in what they can have others do. America's powers and freedoms weren't built on a democratic government, they were built on the lack of government. Voting is much less important.

I like where you're going with the 'more representitives, fewer referendums for less educated countries' though. The full extension is that the relatively uneducated world should be ruled by a supreme dictator of super-human intelligence - self administering and defining the intelligence test, of course. Obviously, myself when very, very drunk. Cheers.
