Here's a little confirmation bias at work... those with kids can't really undo that decision so spending time with the family is a knee-jerk "number one priority" (how many people would really come out and say they would prefer to work than see their kids? even if it's true, I doubt it would be socially acceptable).

Those who prefer the 100-hour weeks will no doubt say work is the number one priority. See "saving money for the future" vs. "spending money in case you die tomorrow" as other examples.
