"MediCare doesn't pay doctors enough to stay in business. Other revenue streams from other payers subsidizes Medicare patients. IF it's all Medicare who will subsidize that?"
I know a lot of docs up here who seem to be doing just fine, and almost all of them tell me that they would gladly settle for less money if they could eliminate all the hassles of dealing with insurance companies and go back to practicing medicine. Something about job satisfaction and professional integrity. My impression is that very few of them are in it solely for the money, but I suppose I could be mistaken about that. I am easily fooled when it comes to things like that. Chalk it up to my liberal tendencies. ;0)
As for Medicare subsidies, if everyone goes on Medicare, we reduce fraud to an absolute minimum, make a serious at preventive care by making a major effort to educate folks on the benefits of diet and exercise beginning in kindergarten, and reintroduce phys ed into schools at every grade level, eliminate the profit making insurance companies from the equation, I frankly doubt we will have to increase subsidies at all. However, I do not pretend to have all the answers to this complex problem. To be truthful, if I were in charge, the first thing I would do is a serious study of how other developed countries are managing to pull it off at a fraction of the cost of medical care here, before attempting to reinvent the wheel. Of course, that would require us to give up our long cherished claims of exceptionalism, which might be an unintended health benefit.
