Credibility!
When you're willing to trade places with a $20,000 a year scamming, robbing, confiscating school janitor who works 40 hours a week pushing a broom, I might start to believe you.
Or, when you find a system which allows such a hard-working, deserving person to make more, and move there. Moving there and making money on this system won't count.
Otherwise, it doesn't make sense. How can you be so robbed and have some much left?
If this isn't fair, find something where you can do better.
