Why do the higher ups in offices like to work such long hours?

This terrible disease is more common in Boomers, who actually got something out of it. Not a lot, but something.

For many people who have no hobbies, aren’t particularly social, and are not all that smart, working long hours was and is preferable to the alternative of no social life and boredom. Many of these types also dislike their own families, so spending time in the office is for them a good alternative to their existence at home.

And some people do honestly like to work. No one knows why, but they do.
