That would mean doctors leaving Medicare and Medicaid, and you might have to pay them with cash or credit cards.
I think it's wishful thinking to believe that doctors are going to be allowed to simply go to a cash-only model. The out-of-control congress will simply draw up laws making it a criminal offense to offer services outside the system.
If I'm not mistaken, Hillary-care back in 1994 made it illegal for doctors to treat anyone outside the government system. It also made it illegal for doctors to choose what specialties they wanted, or where they could practice medicine, if I recall correctly.
I believe that Hilary!-Care included criminal penalties for doctors who went outside the system.
