System X

Take the statement, "Social System X is good for everybody."

If true, it's a compelling endorsement for quite different ethical viewpoints.

Egoists will say "I want X because it helps me."

Altruists will say "I want X because it helps others."

Utilitarians will say "I want X because it helps produce the greatest good for the greatest number."

Hardly anyone thinks you should
oppose a universal good.

Nihilists maybe could dissent
and find a reason to lament.
