I think some people are confusing the point. It's not about whether or not you enjoy your work. It's about the glamorization of working more than others.
I think a critical mass of people have bought into the belief that overwork is equivalent with success. That dedication to work is heroic. So there's signalling going on, a desire to cultivate the image of being a winner (in this narrow sense). There's also naivety... people who buy into this and aren't just signalling but truly think working in this way is somehow reflective of the superiority they desire to possess. So there's a cyclical effect, one group feeding back into the other.
