[영문]With another national health care debate on the horizon, many assume that health plans will present a major source of opposition to universal coverage and other reforms. But a closer look reveals signs of change. Some plans continue their reflexive opposition to increasing government’s role in health care; other plans have stepped forward to advocate meaningful reform. Experience in Massachusetts, California, Minnesota, and elsewhere suggests a clear lesson for policymakers. Sensible proposals and a genuine commitment to cooperation can not only neutralize opposition from a potentially powerful opponent, but can actually bring health plans on board to support coverage mandates, guaranteed issue, and other reforms.
