Actually, the reason for high medical costs, is the lack of free-market forces in the medical field. Patients have very little interface between medical professionals and insurance companies. Fee schedules covering procedures, office visits, medicine, etc., are in a closed-loop system which discourages competition. Originally health care insurance was based on reimbursement to the patient, not direct payments between practitioners and insurance companies.
What you consistently forget, and blather on, and on, and on about, is that you believe that government at all levels, is the solution, and with a few more laws and regulations, we can get to a panacea for healthcare.
Folks who are supposed to be covered under Obamacare, routinely don't buy health insurance; and instead, use hospital ER's and critical care facilities as basic medical care, instead of using regular appointments and preventive care programs which are far less expensive.
In fact, my supplemental insurance premiums (aka Medicare gap insurance) have actually gone down in the past three years (private insurer), while my Medicare premiums have risen the last three years. United Health Care's stock price has risen nearly 80%. Well, no s**t, Sherlock.
That prices for medical care are rising is no surprise to anyone except you. Medical care has a finite number of folks able to perform procedures and can't expand readily to meet rising demand. There have been large numbers of nurses, doctors, and other medical professionals (paramedics, etc.), who've left because of personnel shortages. That prices rise because of shortages in labor is pure, basic economics.
