Life is unfair. Whoever told you it should be was lying to you.
You pay back into a system that allows you to thrive so that that system can exist. The system is much more than just you - it includes everyone. The yield of this very complex system is a certain percentage of rich, a certain percentage of poor and a full spectrum in between. A better system might produce fewer poor people, reducing the need for relatively higher-earners like yourself to pay back into that same system which allows you to do so well. Tweak or change the system or suck it up and quit crying about what's fair and unfair and what ought to be.
In Soviet Russia, you would have other things to cry about.
