As a retired person I’ve always been curious about this. I questioned a friend who is multiple FU money rich. He said he just love his job, and he’s in a position to work the way he wants to work.

Not my cup of tea (and Die with Zero book explains the common sense on this) but I get why though. There is tons of status attached to it, lots of people don’t know what to do with themselves, a lot of identity ( especially in US) attached to the work.
