Perhaps you're working with a self selecting group of Americans.

As a US based developer with almost 20 years of experience across four cities and (as a consultant) many different corporate cultures, I've never met a single person who consistently works 10+ hour days, or more than 5 days per week.

That's a bold claim. How well do you know all your coworkers schedule?

As somehow who has worked for a shorter period of time, I've met dozens of such folk, many of which I have provided support for on weekends or odd times at night.

In either case, anecdotes are not adding much to the discussion.
