I see. In a sense we are already doing that. Minors can not vote (and if I am correct the reasoning is that they don't have the competency to cast a proper vote) and even foreign permanent residents can't either, even though the outcome of the elections totally influences their lives. In a sense these not-allowed groups are already totally dependent on the people that are allowed to vote.

I guess my argument boils down to: We already discriminate. My thoughts are that the way we do it is not optimal.
