As it is now Paul, we have mediocre medical care.  Seeing how the system treats older people especially is eye opening.  Yeah, everything is fine until there is a problem even the slightest non-standard.  Months to schedule specialist consults, months to schedule tests.  It is an illusion that America has excellent health care.  The easy standard problems will be taken care of under pretty much any system.  The harder less common problems are not handled well now and treatment could only improve.  One example of possible radical change is computerization.  Symptoms are symptoms.  A lightly trained person could assist in gauging and interpreting symptoms and feed them together with standard blood tests results into advanced diagnostic computer programs.  The computers would order additional tests if diagnosis is uncertain.  We have the technology to computerize diagnosis now, but the medical industry stands in the way it would cost them money.
