Responding to John Quiggin's lament that we haven't reached a 15-hour work week, Timothy B. Lee claims we're closer than we think:
It turns out that many people have only a limited appetite for "leisure" in the sense of spending their days at the beach or on the golf course. Rather, they’re interested in pursuing creative or philanthropic activities that, when pursued in earnest wind up looking a lot like having a job. For example, as people get wealthier, they’re more likely pursue careers as artists, musicians, chefs, political activists, bakers, winery operators, boat captains, college professors, and so forth.
He later adds:
To be sure, only a small and fortunate minority has a job they like so much that they’d continue doing it even if they didn’t need the money. But the fact that so many successful people who do have options choose less lucrative but more rewarding work tells us something about human nature. Many of us, at the margin, would rather have more "leisure like" jobs than more formal time off. And that’s exactly what many of us have been getting in recent decades.
