Hollywood work-a-holics: are they self-aware or hypocritical?

The more family oriented comedies I watch, the more I see an overarching theme.   The lead man works too much, and because he doesn't have work-life balance, he's missing out in the important things in life -- his family.    Either he's a dad, in which case he's neglecting his kids (e.g. "Liar Liar" and "Elf"), or he's a middle-aged bachelor, in which case he's missed out on building a family (e.g. "The Kid") or there's some mystical convergence where he gets to see both options (e.g. "The Family Man").   Whatever the case, the message is the same.   People (guys) need to get their priorities straight, and spend less time at work so that they can spend more time at home. And I agree with that.   I do. But, I know that Americans in general work very hard, and specifically work long hours.   And I know that long hours are standard specifically in the movie industry.   So, all of these movies pounding home the message that we shouldn't work so hard, are conceived of, produced, and executed in large part by entire communities of people who are working almost non-stop.  What is their attitude, then?   Are they wringing their hands over their own weaknesses as human beings, and sharing their hard-won insights with us?   Or are they cynically writing falderal that they think the audience wants to consume, but which they themselves don't believe in enough to follow?
