Will Wilkinson on Paul Krugman

Agree with him or not (I nearly always do agree with him), the Economist's Will Wilkinson is unfailingly worth reading and pondering.  .  It's on Paul Krugman's bizarre (at least for an economist) lamentation that many people think it good that health-care provision be consumer-driven – or, as Krugman describes it, that health-care provision be "more responsive to consumer choice"  (HT Tyler Cowen).
