There is an entire field of mathematics dedicated to answering such questions and the answer is a lot more complicated than your simple quip. In fact the way most democracies are set up they are theoretically much less optimal than they could be and in some cases are as good as dictatorial systems because of susceptibility to being rigged. As usual wikipedia is a pretty good starting point: https://en.wikipedia.org/wiki/Voting_system.

Would you mind slapping a name on said field of mathematics, because I dig that stuff but only ever stumble upon smatterings of it here and there. I'd love to get to the core of that field. Its like game theory + lots of other stuff. (Sorry for off topic)

It's not one specific subfield but a combination. A good starting place though is probably social choice theory with a bit of a background on Arrow's impossibility theorem: http://en.wikipedia.org/wiki/Arrow%27s_impossibility_theorem.

Awesome. Thank you both!

Indeed :)
