Your comment got me thinking. (The best kind of comment.)

My first thought on reading it was: is that equivalence valid? A society is a collective; a collective functions at the behest of its members. My experience of human nature suggests to me that society will contain members who both are and aren't kind to "less valuable" members. So can, or should, a society enforce kindness towards them, even against the members who are disinclined to be so?

Another related question: should we measure a society's value by its total accumulated success, or the success afforded to its "less valuable"?

I don't claim to know the answers.
