You misunderstood my post. No he doesn't need to listen. In fact, listening is the quickest way for him to lose his job. The fact that you even say this means you partially believe him, and that's a mistake on your part. The only signals intelligence this guy needs or wants is listening to his superiors, and his job is one-way data transmission from his boss to the rank and file. STRICTLY one-way (and trust me, it doesn't matter if his boss is Trump or Obama).
Of course he "talks" with staff and takes questions. Why ? Because despite his wages, he is not all that good at correctly transmitting information, so he is doing this so he might do his job better by having his team interpret his ideas, and try to clarify them to him by asking questions. This is done mostly to avoid the worst of screwups. Only questions that follow this pattern get answered, or even seriously considered (check those financial videos again, trust me you'll see this happen).
He does not have an opinion (I mean he does, but none that you'll ever hear). Remember that. You cannot ask him for it, you will never get an answer. And when you do, because there are amounts of alcohol that will make him divulge opinions, please don't start destroying careers (mostly your own, but you may drag others down) by telling other people what those opinions are.
He won't care about attrition until the ability of the organisation to carry out his boss's orders is in danger, or when his boss cares. Nothing other than that can make him care. But he's paid a LOT of money to make you think he cares.
