Just be because someone wouldn't survive against a saber tooth tiger doesn't mean we're interfering with natural selection or that it reduces our survival rates. If we discarded our "weak" the way primitive societies did, we wouldn't have discovered people like Stephen Hawking and John Nash. Our species' altruism and shared survival gives us a much greater pool of potential skill, labor, and creativity to draw from, and these potential contributions help each member of our species as a whole survive better as a result. Just as we didn't know a millennia ago that one day Einsteins might be of more worth to our society than skilled hunters, we can't necessarily foresee what might help us in the future. What if the 'retards' you want to cull from our species turn out to be the only ones with genetic resistance to a future epidemic, for example?
