To be fair, one could argue for dust specks without Felix morality by weighing increases in individual's happiness with diminishing returns such as to asymptotically approach some limit. (But then you would sacrifice one individuals arbitrarily unimaginable happiness just to bring someone else an arbitrarily small sliver towards baseline)

Since it's meaningless to call dust specks "right", just consider it true if you want to. I don't want to so I don't.
