Aunty,
Of course doctors are leaving for higher pay. If we had a single payer program, that would be eliminated. Is that what you are arguing for? The way the system is run right now, the doctors have plenty of work for higher paying private insurance companies and so choose to omit certain programs.
There is also an incentive to limit the amount of participating provider. The question is whether or not we truely want a market driven health care system. If so, should everyone who wants to be a doctor be able to start his or her own practice without intervention. Once we allow any intervention, then we have a problem. We limit the number of qualified providers, then we allow them to charge what ever they want for a resource we all must have.
I guess its all ok for you since you can get that resource and others can't. But already you are squealing about how there is a lack of doctors willing to take your program. Eventually you may have to supplement more and more of your care until you are where we all are. Basically unable to do it.
