In a free and open society, there will always be some who will work towards their own best interests to the detriment of the society as a whole.

As long as there are more people who work to the benefit of the community, we should stand a chance.

the one who survives is neither the smartest nor the strongest but the one who is most adaptable to change.

Sounds a lot like "Even a BlindSquirl finds a nut now & then" assuming that the BlindSquirl learns to forage for nuts at night, when predators are less likely to see them and the whole "blindness" thing isn't as much of a disadvantage.
