The problem is that typically the burden of work is much more than 40 hours, even if you only work 40 hours. Because those hours are calculated in the most ungenerous way possible.

Your lunch doesn't count. So that's now 9 hours at work. Your morning commute doesn't count. So that's now 10. And your evening commute doesn't count. Now up to 11. And those after-work meetings don't count, but you kind of need to attend them because of the implications. And so on.

While you may "work" 40 hours a week, you certainly contribute to work much more than 40 hours. For me, it's over 60, and from what I've seen that's fairly typical.
