The root cause problem with health care is its cost.  I am sad that Krugman let's his partisan issues dominate the discussion rather than addressing the core real problems.  He blithely suggests the Obamacare has brought premiums down even while the state of Oregon is telling us that increasing costs of health care coverage stand as one of the reasons for the massive state budget deficit.  I suspect that the total real dollar amount paid to the health care industry since passage of Obamacare has risen dramatically.  Yet, because of the partisan and special interest drive to obfuscate the matter, no one talks about such things.  Krugman, unfortunately, avoids the hard issues.  Obamacare does not address the overall cost issue in terms of actual annual net cost for health care.  As an economics Nobel, he owes us better.
