I wonder when the Mexican public healthcare provider, the Secretariate de Salud, will apply to offer exchange plans to Arizona residents in underserved counties. The Mexican government would make money (based on prevailing US insurance prices) and Arizonans would finally have a "public option." Yes, some creative methods would need to be employed to get patients to the existing providers (until Mexican clinics could be set up in Arizona), but that seems to be a minor problem when considering the long-term win-win aspect of this proposal.
Actually, most Arizona residents already have good health care insurance options. Those on Medicare, TriCare, Medicaid, or covered by group health plans now total 90% of the population, and they're fine. Telling the remaining 10% to go to Mexico is one option. Another is to stop treating them as a separate group, or stop letting the insurers pick and choose their customers and apply the same rules to them that they want from us.
