This is probably the point of confusion. In most of Europe, at any rate, salaried employees are subject to the working time directive: http://en.wikipedia.org/wiki/Working_Time_Directive
I can choose to work over that amount, and time worked over those 40 hours is time-in-lieu, which I can take off pretty much whenever I want (although I have to get approval if I want to take more than one day off at a time - but if it's just a day, or half a day then I just shoot them an email that morning)... My company are a bit more flexible on taking that time off than a lot of places, but apart from that, the conditions are similar to a lot of other places...
I guess what he's getting at is that the US is a pretty terrible place to work and live, gilded though the cage may often be, and it is hard to disagree.
If you are exempt (Salaried) - you basically work when your manager tells you to. I've been at (several) companies where we had 3-4 month death marches with _everyone_ working late and on weekends in the office to push the ball over the line.
