The fox and the grapes: is real reform beyond reach in the United States?

As the challenges of maintaining (or, in the US case, attaining) affordable universal coverage multiply, the debate about what constitutes "real" reform intensifies in Western health care systems. The reality of reform, however, lies in the eyes of myriad beholders who variously enshrine consumer responsibility, changes in payment systems, reorganization, and other strategies -- or some encompassing combination of all of the above -- as the essential ingredient(s). This debate, increasingly informed by the agendas of health services researchers and health policy analysts, arguably serves as much or more to becloud as to clarify the practical options policy makers face and remains severely imbalanced with respect to the institutional sectors on which it concentrates, the fields of knowledge on which it draws, and the roles it envisions for markets and the state.
