When you have a family that you love and enjoy you already have the large reward. Work you enjoy is icing on top of that. The reason you may seek less risk with family is that the upside is relatively small (it will always be dwarfed by family), and the downside is large (losing your home, putting financial stress on your family, etc..).

But I agree, they shouldn't be criticized for being dedicated to their job. But I do think posts, like Don's, seem to implicitly criticize those people who aren't at the cafeteria at 8pm.
