What drives me crazy about this is how it shows that some employees are expected to bust their asses to meet deadlines, but others (legal) are not -- oh, if legal won't be done in time, we'll just move the deadline, no problem.

While some people -- healthily or not -- are willing to bust their butts (with or without extra compensation) when they think everyone is in it together, it will generally kill morale and willingness to do such when you realize when someone else 'doesn't have time', the deadline is moved, it's only you expected to work evenings and weekends and extra hours to meet the deadline. Why is your work-life balance less important than theirs exactly? (Only because they can get away with it...)

And while not always as stark as your example, people are often shown this all the time, that not everyone's inconvenience is in fact treated equally, that the "deadline that can't be missed" really only applies to some people, and is moved for others.
