There are a lot of examples on an even much larger scale. I know two folks who have sold businesses and now live in Hawaii doing practically nothing. It's really not that uncommon. It's just that those folks fade into memory while the workaholics continue to work and increase in overall profile.
It really feels a lot like the 90 hour work week insanity of the tech boom. For years after that I encountered business-types who would enthusiastically tell me during interviews that they're "the type of company where developers keep a sleeping bag under their desk". Apparently that's the key to success, except that very few of the startups I've encountered actually operate that way.
A bunch of startups that I've encountered operate that way, but there seems to be a strong negative correlation between sleeping at the office and the eventual success of the startup. The ones I know that succeed work hard, often 9-10 hour days, but their employees have weekends and aren't at the office all night long.
