I don't know. It seems you are confounding a couple of issues. First is the scope of the article. It seems more of a policy for good practices to adhere to in treating employees. Even if you are a marathon runner, it would not be in your self-interests to require long distance running as a job criteria. Secondly is motivation. The motivations of a founder are often counter to that of an employee. From the perspective of many employees, job satisfaction is much more desirable to a high reward outcome - irrespective of dedication, hard work, or talent.
While you know your experience, you don't have access to the alternative futures that might have resulted given different behavior. Which is why personal experiences and anecdotes do not substitute for actual causal analysis.
