I don't mean to look down on this kind of group, I am probably one of them. There is nothing wrong with people enjoying a good work life balance at a decent paying job. However, I think there is a reality that if one wants a world-best company creating world-best products this is simply not good enough. Just like a team of weekend warriors would not be able to win the Superbowl (or even ever make it anywhere close to a NFL team) - which is perfectly fine! - the same way it's not fair to expect an average organization to perform world champion feats.
