The kids did actually pull something out of the wife swap though. They learned at a young age just how important education is.
And it was nice to see the stupid people change their diet... though I would've preferred them to eat themselves out of existence. Does that make me an asshole? Certainly does.

AD-36)), but that doesn't mean that natural selection shouldn't be allowed to take place. If modern medicine weren't so much about prolonging life (in some cases past the point it should, to where the person is in so much pain and they want to just go (I've seen it happen, I was not a fan) then population levels would remain at a tolerable level... there would be less starving people in the world. Aside from that society as a whole would be more intelligent because the stupid people would simply naturally select themselves out of existence.
