So, what do you want to give up?....Mri's/CT's?...almost everyone who goes to the hospital with headache/dizziness/etc gets one. Why?....The docs don't want that person to leave and 2 days later drop from a CVA...doesn't look good. Wanna give up bi-ventricular pacing defibrillators? To the heart failure patient that is $35,000 (device only 10years ago) well spent. Maybe that 80yo really doesn't need that hip replacement; after all the remaining life expectancy may not justify the cost, right? Thing is, you may be OK with those things until it is you or your family....then....eh, not so much. Rationing is simply a result of socialized medicine. Too many patients and not enough resources.
Your comment: And if a Medicare-for-all type plan is properly structured, the total cost should be less than what is now paid in taxes and insurance premiums.
You remember the old definition of a camel, right: It is a horse designed by committee. What committee do want designing your medical care.
I could go on with this stuff for pages but I think you begin to get the idea.......
