You say that as if it's necessary for human kind to improve. We don't have control over what happens to our species and we will go extinct which is absolutely fine. Not sure what is up with this whole obsession with continuing the species. Stop worrying about something that will naturally work itself out instead of complaining that the 'wrong' pe ople are breeding. Maybe thats just the natural way of things. I mean, greed, violence, hatred and discrimination are all ingrained parts of the human animal meant to aide in the whole survival aspect of things. It wasn't meant to catapult earth species into space. Unless you are ok with genetic engineering and removing those traits from the gene pool you will never not have power hungry assholes ruining it for the rest of us. And that's fine. That's just what life on earth is like.
