Technically, we're not supposed to live in a democratic society (the U.S. at least. I'm pretty sure Canada is in the same boat). We're supposed to have a constitutional republic. The founding fathers of the U.S. even said that democracy is the worst form of government. In a constitutional republic we vote for people who will represent the views of the common folk to the government. They are affectionately referred to as "representatives."
Alas, our society has degenerated into a democracy. We have mob rule. 51% of the population controls 49%. Someone once said, in fact, "In a democracy, two wolves and a sheep take a majority vote on what’s for supper, while in a constitutional republic, the wolves are forbidden on voting on what’s for supper and the sheep are well armed."
Also, we have something called the "electoral college." I'd just like to formally say:
Oh, as for the perfect type of government, I'd say a democratic robocracy is best.
