fwiw i think there's a balance here
at my current company i happen to work 70hrs/week but it doesn't feel like a ton of work, i'm having fun and let's be honest a chunk of the "work" is meetings & hanging out with my coworkers who are also my friends. the vast majority of people's productivity drops off after 4-6 hours of focused work. if i wanted to rest and vest there's plenty of companies to do that but your upside is capped hard
a company that 'requires' 996 doesn't understand why people work that hard in the first place.
