Sandberg is credibly the COO of Facebook, but TIME didn't give her the cover to appeal to the 7 people who will hold that job between now and FB's eventual bankruptcy in 2047. Or the 70 people who will compete for it, or the 7000 people who will be in similar positions across the Fortune 100. She's being held up as a model of success, for the average person to emulate. It is very much an open question how many people would consider life like hers well-lived.

That the difference is glossed over so blithely makes me skeptical.
