Come on people, you are all forgetting some very important, and basic facts.
First and foremost, Dave is in the process of making a name for himself, one that will bring him hundreds of millions, if he makes a player out of this dog we call US. (Tens of millions, should he fail at this point) The fact is, it's not about money with his kind, it's about ego, and face, he is not going to give up at this point. Good old Dave is just looking to get all that he can, while the getting is good.
As for Bronner... He is even sharper than Dave, which explains why he manages money, rather than trying to make it as a CEO, or in any other working position. Of course he wants it all, so would you if you were in the drivers seat!
The pension plan? Who cares, let the government take it over. We have all been told over, and over how the pilots have all the brains, so I'm sure they have planned for such an event. As for the rest of us, it won't make a bit of a difference.
To end, chapter 7 is close the doors, sell the farm, and move on. This will happen, or not happen, regardless of what we the employees decide, it is way beyond our control. To fret over 7, is to worry as to whether the sun will rise, if you have to ask, it's too late!
