Far too simple. That has peen one of the possible fixes but the left does not like it. Actually that is close to what we have now since most doctors are self employed and pay all their office expenses out of the fees paid. Where we run into difficulties is when the problems require expensive treatment like transplants or drugs. Here the government health care industry has a lock on service and the costs are out of control. ER is run like a walk in clinic which is neither cost effective or sanitary.
I think we will eventually move to a two tiered system of some kind when enough people realize that the current system is not sustainable. Everyone will be entitled to free basic care but after that what you get will depend to a certain extent on the amount of premiums you pay for a bundle of services much like life insurance. To a certain extent we even have that now with some union health plans. For a larger monthly fee you can get a private room and all sorts of extras.
Don't hold your breath- after decades of demonstration that the single tier system isn't working, the powers that be still can't see it, maybe what it boils down to is idiots who think repeating the same procedure is eventually going to get different results. :lol:
