Unfortunately doctors are completely ignorant about the financial aspects of this.It's rather mind-boggling to have someone say they're completely ignorant on the financial end of things but simultaneously replying and seeming to defend what happened.
I remember helping a friend get plastic surgery, dealing entirely with a physician for the surgery before hand and then arriving at the hospital and being handed a request for several thousand dollars for the hospitals end of it. And when this was broached to the physician, he made noises whose meaning were somewhere between "I just work here" and "isn't that what you expect when you go to a hospital?".
I don't see any good solution to this problem, especially as we're taught in med school that the patient's health is the most important thing and financial aspects should be secondary.
I'm not sure why you knowing how this works means it is insoluable. An obvious solution is the California bill which keeps hospitals and doctors from making such outrageous charges (of hospitals think the consultants are necessary, they can find a way to engage without the out-of-network charges - as a "your problem, you should solve, not us" thing).
The sort of discussion veers in just weird implications - "I'm a doctor and I'm ignorant of these, that means you should be too and you avoid considering obvious changes to make thing more rational just as I do..."
