Many, if not most, Americans are probably not being paid for that lunch break, and are in fact working 0800 to 1700 or something along those lines for an actual 40 hours. That's how it was for me the last regular "9-5" that I had 10 years ago, and I'm pretty sure things haven't gotten better since then.

I don't know if all european countries. But here the 30 minute break is also counted as work hours.
