There's a human factor to all of this. An executive's day is not (typically) spent coding, or looking at spreadsheets, or analyzing forecasts. Those may be parts of an executive's job, but the bread and butter is working with people. Coordinating other's efforts - whether to maximize shareholder value, build a particle accelerator, make a movie, market useless crap to consumers, or whatever - involves a lot of dealing with people, successfully navigating complex interpersonal relationships, making compromises, etc. Some people really thrive on this and derive joy from the work itself. I personally find it exhausting, as I suspect do a large number of the people who frequent HN.
