My brother is a doctor at a VA hospital. He does not think it will change much for VA doctors or patients unless funding gets diverted. For regular doctors you have huge new government agencies to be paid. Prices will go up. Payments to doctors will go down. Malpractice lawsuits will go up. No one will want to be a doctor and doctors will retire in huge numbers. Citizens will be paying a huge amount for care that will be heading toward nothing.
Man! Look at the OPPORTUNITY that you are outlining. Medical care will continue to be needed at a price that people are willing to pay. Some smart person is going to open a clinic and a transportation service to provide for those people who are willing to pay. Mexico? Canada? Costa Rica? I don't know where, but someone is going to hear the clarion call.
I'll be surprised to find that someone hasn't already put this into place.
Obamacare will affect everyone. Many doctors are going to retire, taxes on medical device makers and other health care industries will increase putting many out of business, and millions of new patients will be added to the system. There will be rationing, shortages of drugs and medical devices, lowering of standards to cut costs, and really long waits for care. Nobody will be out of the reach of this disaster except our overlords in Washington.
