The larger question is whether the selection "mechanisms" would be stable enough to prevent the re-emergence of egoists, given the improbability of NS wiping them out. One can't refute egoism any more than one can refute capitalism.
Darwin's quote is the perfect apologia for imperialism and racism. Isn't the quest for advantage itself antithetical to altruism? Also to the extent that altruists are "locked in" to a struggle against egoists, isn't that, too, just a different form of social Darwinism?
