My argument is that DNA lays the foundation for skill-honing. Without the genes, the work doesn't matter. If you want to make a value judgment based on that, that's fine, but it isn't very scientific. Both things contribute to success, but one literally relies on the other. For the average human being, work probably contributes more because you're talking about competition between relatively similar levels of talent. When a group of people all have similar levels of talent, their work is all they can rely upon to differentiate themselves. For people with better DNA, less work is required to achieve similar levels of success. A hardworking person with athlete genes can be just as successful as a lucky person with average DNA, but that's another argument altogether since we're not really discussing luck or game theory.
