"that it's somehow morally wrong they get rewarded for it"
Oh, poor little rich exec would like some form of recognition other than a rather large bank account.
Be still my aching heart.
Okay, let's make two things clear : success in any computer game is a time-limited proposal because, as any StarCraft II top-lister will tell you, you get old and your actions per second are inevitably going to go down, meaning you will be replaced by someone younger sooner than later.
So, just like professional sports players (which earn 10x more), your time in the limelight is on a schedule, and you don't have all that long to enjoy it.
CEOs, on the other hand, not only get 1000 times the salary of the lowest ranks, they also have this thing called a Golden Parachute, which nobody else gets, and which allows them to absolutely screw everything up and drive a company into the ground and yet still waltz away with millions in severance pay.
THAT is immoral.
So cry me a river, asshole.
