re: Make a case for why voting matters.

as we all know our forefathers formed a republic. besides the electoral college we're pretty much a democracy at this point.
saying that, if you didn't know anything about governments and had to form one, and someone came up with the this idea.
let's give everyone one vote. doesn't matter if they're the most productive person in our society or a complete moocher and if the moocher is to lazy to get off the couch and vote we'll come to them.
how in the heck is that going work?
