I don't think anyone disagrees with you that there may be an outlying segment of the general human population that can "outwork" others in certain, specific circumstances. However, I don't think this advantage is genetic, and is more likely a function of age and lifestyle, both of which will change over time. Not only that, these outliers are often below average in other important areas like fitness, communication with others, and personal integrity.
