A lot of people get satisfaction out of their work. I know I do. I don't see it as an exploitive relationship with my employer, although I'm fortunate enough to have a job that requires cooperation and creativity. Maybe I'd feel different if I were an Uber driver, though, but maybe not. Even when I had menial jobs (e.g. lifeguard, pizza delivery driver), I got satisfaction from providing some kind of value (e.g. watching over children, delivering pizza). My least happy time was when I had a meaningless desk job doing essentially make work (e.g. creating reports that no one will read, tying out numbers that no one cares about, entering in data that one one notices).
People like Bezos similarly work long hours so its not like they're idle while expecting others to work on his behalf. I imagine Bezos continues to work because he gets great satisfaction from work. He would never be able to consume all his wealth in goods or services in his lifetime or the even his children's or grandchildren's lifetimes.
But look at people who don't work. Even if they have a safety net, their overall satisfaction is much lower than those that work. Mental health goes down as well as substance abuse and other destructive practices.
Of course the poor mental health and substance abuse may lead to unemployment, but I think there's something deeply unnatural about not engaging in meaningful work. Most people don't have outside creative outlets that give them meaning. Without a traditional
work relationship, these people are adrift. This may be out of fashion, but I would encourage my children to find work early on rather than waste away their time playing video games or watching TV.
