we are a social species by evolution, and like all such species we have an innate drive to help and protect at least those of our own in-group clan. And this impulse can be - and is! - extended to wider society, and in it's most refined form to the whole Earth, and all its living kindred. Even in this fragile extension, it can be encouraged as a widespread agreement with which most will concur without too much stretching: a basic religious truth that most will accept.
Truth is that the sick-minded enemies of socialism have to work continuously to suppress this entirely natural, instinctive tendency in humankind. I've noticed that the cry 'Socialism doesn't work!' has begun to be sounded quite a bit more lately. I surmise that this is because the doctrinaire bigots of socialism-hatred have noticed that disillusion with anti-socialist neo-libconism is widespread, and is causing socialistic inclinations to come back into fashion again. Oh how that does upset the bigots...
