I have seen the health care system from both sides of the desk, as it were, since I am the part-time business manager for my wife's part-time psychology practice. Yes, our health care system has serious problems. They mostly predate Obamacare, which only slightly exacerbated some of them.
First hint of the problems: there is something called "the medical billing industry", which neither provides health care nor insurance to cover health care expenses. Between the AMA , the Federal government (esp. CMS a part of HHS) and the insurance industry (which is regulated by state regulators in what is surely a prime example of the phenomenon of "regulatory capture"), for a physician or allied health professional to be paid, the activity they are being paid for must be classified by a bizarrely complex system involving diagnostic codes and procedure codes. There is a whole industry of "coders" who are paid by physicians and hospitals to classify their activities for the sake of filing insurance claims -- typically taking in from 8% to 10% of what is collected on the claims. (Incidentally, the "Medicare for all" proposal the Left has floated will make this worse -- Medicare is the most rigid of all insurance programs in demanding all the niceties of this abominable classification system be adhered to. Amusingly, the easiest insurer I have to deal with is Oklahoma's version of Medicaid -- maybe single-payer, provided it is run by conservative Republicans, might actually work.)
Second hint, reimbursement rates paid by insurers are proprietary and subject to non-disclosure agreements. How the h*ll can you have a functioning market if price information isn't public?
Third hint, all cutting-edge medical treatments (both pharmaceuticals and medical devices) are provided by artificial monopolies. Why? Because Congress has the power to grant monopolies called "patents" and does so without regulating prices in the public interest as prices of "natural monopolies" such as utilities are regulated by the states.
