Some are suckers. Some provide succor. Some are sucky. It takes a village to raise a child. It takes all kindsa people to make a world. Why?

Why not live in a world of those who provide succor to one another? Why do we need suckers or sucky people who prey on them? Why can't we do without the cold sores and zits among us and just have "nice" people? Any logical reason you can come up with WHY a world of kind nice honest people wouldn't work better than the despicable grotesque ugly degenerate one we have now? I'm listening.
