Definitely this.
We let work take way too much time from our lives.
If you count commuting, the minimum 8 hours at work (more like minimum 10) then work can eat up to 12 hrs/day.
On top of that us 'knowledge workers' carry our work around in our heads all the time.
It's not as though after 8hrs we just put the wrench down and go home, no the ongoing problems of work follow us around and even toss and turn us in our dreams sometimes.
To me this is unacceptable.
The way that we employ our working hours is a waste of time[1] on a colossal scale, and for little benefit to humanity most of the time.
[1] Literally the finite precious time we each have on earth.
