Life is never fair. not for humans and not for any living being.

If you try to make it fair by paying the person with lower skill same as skilled person, the skilled person won’t feel the need to use their skills anymore.

To make it fair you need a magic mirror that print statistics about each person (skill level, talent level, physical strength) and use these numbers to decide who used all their abilities and who pretend to be dumb to avoid using their brain/body

Is there any system that reward talent, hard work or skill ?

I think the main reason is that in the future when training Calude on data obtained from the internet, they could discard first all data that were produced by claude in the first place.
