I cannot believe people can actually think certain votes are more important than others or that peoples' votes don't have value.

If a person is unable to manage his or her own life effectively, that person probably shouldn't be managing the lives of others. We've been over this one before a bunch of times too.
You can go down that road all you want. I think it's fundamentally wrong. I'm sure your opinion of what managing a life effectively is, is completely different from others' opinions.
A basic facet of our system is that everyone is supposed to have a vote and everyone's vote should be equal. The millionaire should be equal to the homeless guy as far as their say in who represents them goes. Any effort to filter out voters based on their education, lifestyle, religion, race, anything else other than age is a failure. Someone is not getting their proper say.
