You got the skills. You get an opportunity. You excel, prosper and rise up. However you know this is all fickle. Someone with better skills might usurp you. What do you do? You try to cripple opportunities for everyone else. That next talent will never be discovered, there will be no one to usurp you. You win, that's all that matters.
Greed gets the better of everyone in the end. History is filled with these examples. You either die a hero or live long enough to see yourself become the villain.
How have we addressed this weakness? Lowering the standards for those less fortunate in hope of discovering that next talent.
Now, since Greed always gets the better of humans in the end. So the definition of less fortunate itself has been corrupted. The solution we devised to address a frailty, to right a wrong is now the villain.
