It's one thing to scoff and believe "Oh, it's nothing! You're just holding us all back!"...
...Right up until a plane load of freight or people plunges out of the sky.
Free market economics optimizes for one thing, and one thing only as a first,order optimization. That's why we regulate. To ensure that all those nuisance secondary facets are accounted by everyone equally to ensure that market forces natural race to the bottom doesn't compromise the central tenet of air safety; that everyone and everything that goes up, comes back down, safely, controlled, and alive.
The business part, if you think about it, is secondary to the capability to make and safely deploy a new plane. A nice bonus.
Sacrificing the quality of the final product for the sake of looking better on the balance sheets us a cardinal sin. Plain and simple. Based on testimony from inside, that sin seems to be SOP at Boeing for the better part of the last decade.
This in turn is because getting a new airplane type to market would cost some (I assume, facts are welcome!) unholy amount of money and time to get approved.
If you consider that decision "greed" or "a rational response to perverse regulatory incentives" is I suppose a personality test as good as any :)
