Your natural talents are not your own doing. You're simply lucky to be born that way. For example, Michael Jordan was born with talents and gifts. (Of course, if you replace the politically correct term "natural gifts" with the identical term "genetic talents" many people get very agitated!)
Did he deserve all the money he made? Certainly Michael Jordan practiced hard, but many other players practiced just as hard, and perhaps his willingness to practice hard was also an inborn trait. Jordan was also lucky to be born in a time when we value basketball talent, and reward it with millions of dollars in compensation.
The same can be said for Wall Street bankers. They may be born with certain natural talents (analytical ability, mathematical ability, love of risk, etc.). If a hedge fund manager makes a smart bet, he can make a billion dollars overnight. But it's a lucky bet. How does it differ from someone who wins the lottery? Does he deserve the million dollar bonuses? Or is he simply lucky to be born in an age that honors financial acumen (i.e. the genetic traits that lead to its development)?
Such inequality in innate traits is the rationale behind income redistribution. The rich should pay more in taxes, as the genetically disadvantaged suffer from a lack of natural talent (intelligence, diligence, energy-level, etc.) and should be supported by social programs, essentially handouts from one genetic class to another.
Yet, in one way, Michael Jordan is responsible for his success, because talent is not something you have. It's something you are. It's part of your design, which comes from your genes via development. Michael Jordan is functioning according to specs, according to his genetic design.
The same way that a serial killer is operating normally when he hunts down and kills someone. It's the way his genes designed him. He enjoys doing what he does. He's operating according to his design specification. He (the complete organism developed by his genetic blueprint) is responsible for his acts, and thus should be punished for his actions. Because laws are simply rules imposed by one set of genetic beings over another.
If you're not happy about this, there's not much you can do. Human development is mostly one-way. The only way to change the outcome is at conception, although meritocrats are desperately fighting this option.
