The Good Samaritan

The Good Samaritan
The story of the Good Samaritan is well known. Portraying concerned altruism.
However altruism faces a subtle hurdle, in that it may be interpreted as purely what people do for each other individually.
If this is made a universal virtue, or globalised, then all people on earth should be kind to each other and treat everyone equally, at least where others do likewise.
But this is essentially short-sighted, and narrow. It deals with the person in isolation and in immediacy. If the future were brought into the equation, it would essentially involve society at various levels from family to nation. Not only that but how those societies relate together and to the whole world.
Ethics to be meaningful and even remotely complete includes how national societies, or whatever equates to them, live together and survive against the intemperate demands of others.
