Yea, I think that’s comfortable for many people. I think I would enjoy working 35 hours a week. 90 would be about 45 per person, which I would think is the maximum for “lets work and have a life too.”
Some folks make work their life – good for them if they want, but it de-emphasizes a lot of other things, like family and community. Then again, a lot of people work that much… because they have to.
I guess 1999 never really arrived…with commute, I know so many people who work 55+ hours a week, and those tend to be skilled, high paying jobs. It’s worse (in the US, at least), for unskilled workers, who often have to work the equivalent of two full-time-ish jobs to get by
