Here's a good example of not earning: being born with an extremely athletic body that ensures he/she will make millions or billions as a professional athlete. That person did not earn his/her body, they were born with ... a lower caliber athlete who was not so lucky to be born with what it takes could work just as hard if not harder and never make it.
So technically the latter less able person is working harder and the star athlete is just reaping the rewards of their lucky innate abilities. What does earning have to do with that? I don't understand why you can't see that, in life, we are dealt cards and everyone does their best to play those cards. Unfortunately, some are born destined to make more money and they didn't earn there money, they were dealt a lucky hand.
