Compare your straw man to a CEO, who’s responsible for 10,000 families being able to pay their bills and feed themselves. All you’re describing is being lower down a hierarchy, which naturally tends to come with poor stress management and high sensitivity to negative emotions.
You also seem to be quite ignorant to what a CEO does, and the stakes of the position. Failure for a CEO can end your career, regardless of whether you’ve already established yourself as entirely financially independent. It is also by definition the position of greatest responsibility in a company. There is nobody in a company that faces greater pressure to perform.
If you fail at your job, it’s really unlikely that your failure will be dissected in the news paper for everyone to see. You could get fired and go out and get a new job. For a disgraced CEO, this is usually not an option. We could all point out a couple of examples of revolving door CEOs, but for most executives, this isn’t a career path or even an option.
