A core component of that film is that the higher you go up the corporate ladder, the more distant and ignorant the individuals are. Further, they wear their distance and ignorance with pride - they have the luxury of remaining distant and ignorant and they're not afraid to flaunt it.
Don't get me wrong: it's a great scene, and speaking plainly is always something to aspire to, but the individuals in those scenes are supposed to be viewed as somewhat monstrous and lizard-brained.
As another commenter said, the film was trying to make the opposite point: that Irons’ character knew full well — probably better than the other characters — what was going on.
But the detachment you mention can / is very important. When you’re working deep in the woods you really can’t see the forest for the trees. You may be working on a feature that will make the user’s life a lot easier, but the real customer is IT and your feature could be cut because the customer won’t like it (“this will add retraining cost”). In Margin Call, perhaps the thing that could increase your bonus is, from the overall company’s PoV a distraction because it’s more urgent to save the company (so bonuses can be paid out at all).
So a good manager operates at a higher level of abstraction. The best ones have a lot of experience so can see from the signals they get what’s happening at the lower levels of abstraction. Irons’ character is supposed to be one of those.
Of course the high level abstraction, when the boss fell upwards and doesn’t have the Fingerspitzengefühl to be able to see what’s below the surface, is a common problem. It can kill a company: look at how Welch and Immelt destroyed GE.
A good sign of this is also called out by a different commenter: opaque language is often used to try to cover up ignorance.
> is a German term, literally meaning "finger tips feeling" and meaning intuitive flair or instinct, which has been adopted by the English language as a loanword. It describes a great situational awareness, and the ability to respond most appropriately and tactfully. It can also be applied to diplomats, bearers of bad news, or to describe a superior ability to respond to an escalated situation. The term is sometimes used to describe the instinctive play of certain football players.
The context is that Jeremy Irons' character knew exactly what was going on, he wanted the risk analyst to state it to everyone else in the room, and keep him on track and focused. Right before that meeting, there is a scene as the characters walk in where they are warned by the CEO's right hand man not to try and bullshit, since he would know.
I don't disagree with anything you've said - I was trying to make a tangential point: while the CEO is ignorant of financial analysis, and the quant is ignorant to the business ramifications of said analysis, both people lack humanity: neither character gave a damn about the wider consequences of their company's actions.
Steve Jobs may not have cared much for individual people, but for all his faults, he really did seem to care about humanity (in his own way). He preferred plain language because he deeply valued shared understanding, not because he wanted to flex on his overly cerebral underlings.
