Two counterpoints: A. The sum total of all humans alive at moment X are fit to be alive at X and have an equal fitness of survival. Divergence occurs when we talk about probability of surviving in future time frame Y. Even so, criteria that defines current and future fittest in "survival of fittest" can be many things. Dinosaurs roamed the earth, but mice survived whatever killed the huge, strong lizards. B. A society that does not care for its least might find that its least are not loyal. This can have security implications, especially when bordered by unfriendly states.
