My skills can provide more value than others. It's natural that my pay is not equal to others.
You're going to have to elaborate on that, because AFAIK humanity has not solved intelligence to the point that we can say it is entirely nurture. That makes it reasonable to assume that it is part nature, which means that yes. It is genetically better than others' brains. And there's nothing wrong with that.
You don't believe success is a combination of nature and nurture?
