The patient should pay the same, no matter who does it. Compensation of healthcare staff is an internal matter and frankly not relevant to the patient.
So should every healthcare provider organization throughout the country be required to charge the same price for a given procedure? Many US doctors still run solo practices, so there is no real difference between the company and the "staff". It seems reasonable that doctors with more experience and better skills should charge higher fees.
That's how it works in Germany.
