That's not the case for everyone. I have a friend in US , could have retired 6 years ago, owns 21 rental apartments , has over 5 million USD cash in at least 1 account I have seen , and is still working at our old job. His accountant has told him working at the job is crazy as he would still be getting 80% of his pay if he retired. His rents pay him more in 2 months than he makes at job all year. Some people have no outside social life so going to work ,meeting people is the only social interaction they get. Would be lonely without it. He has no wife , no kids and has been to Thailand before so knows how nice it is.
Another co-worker also could have retired 6 years ago died in January from Covid home alone. No wife or kids. Simply coming to work as that is the only friends he had to comunicate with. Not sure how much money he had but he never had a passort and never traveled on vacation , only to music concerts in the state.
