I should add that the right way to count these hours is including both the "productive" work, and associated activities such as learning new tools or "working" on pet projects, i.e. things you do for fun/passion but are also a career investment. Considering also that these "extras" are often easy to accommodate without big sacrifices—reading a book in your long bus/train commute, hacking in your laptop while watching the kids, listening to tech podcasts in the gym, etc.—a 60h week may be perfectly normal if it includes everything... and even 70-80h not too bad if that number includes ALL your computing, up to reading HN ;)
