Even "Fairness" isn't quite as useful a metric - where do you draw the line between things that should be eliminated as being unfair and things that are valuable culture and individuality? Parental intelligence is strongly causally coupled with their children's future intelligence simply through their working vocabulary and talkativeness, which is clearly unfair from the perspective of the newborn child; how do you fix this unfairness without invasive changes to home life starting from the minute the family goes home from the hospital?
And, of course, this entire thing is a symptom of fixed-pie mentality. When inequality exists - when some people have bigger slices of pie than others - people seem to be reliably made happier by throwing chunks of the pie on the floor as long as they're someone else's chunks of pie. They're happier about throwing away chunks of pie than they are about getting an entire new pie to split up. It really bugs me when I see "fairness" valued over actual goodness.
