My first reaction when reading the title of this article was to think of a variation of the punchline for an old _macho_ joke: "because other men pretend to care".
In my experience, and granted I haven't worked in the US, the number of hours you spend in the office is always expected to be in line with what your manager has committed to paying you for.
In countries like Germany or Holland, if you consistently stay over-time in the office you might be surprised to find that you will be called upon justifying your behavior since the local belief is that you are either incompetent and can't finish the work assigned to you in your normal work schedule, which will cost the company money to train you or hire a replacement, or your manager is incompetent because he over-assigned your time and it will cost the company money when you finally burnout or start taking shortcuts in your work.
Other European countries have established rules that forbid employers contacting their employees (mail or phone) outside of business hours to avoid the pressure of having to do work on your personal time.
I don't want to start a "war" about US vs insert-European-country-here productivity but, honestly, do you know anyone who actually does measurable quality work for 16h straight in a consistent way?
