It’s a weird exceptionalism which celebrates excessive work and all the impact that has on people, and vicariously relate to the rare successes as if they’re your own. Most people won’t ever be a billionaire, and even those who will won’t always be happy with their life. One of the few things almost every person has, as almost equal currency, is time. Almost all of us spend most of it doing work for some external purpose and get to enjoy little of it ourselves. I’m not sure how much joy people get from being successful at business or entrepreneurship, but as a value judgment I’d say that people who live their lives satisfied and healthy without such achievements are probably treating themselves better than if they were chasing an improbable windfall.
As for which culture is “better”, I don’t have to comment on which is happier and more satisfied. That much is knowable.
