Places like the Bahamas, Puerto Rico, Northern Mexico, & the Caribbean islands may very well wind up as medical Meccas. Doctors could move their practices to such places to provide quality care at an affordable, cash prices, free of onerous US bureaucracy, monopoly insurance companies, & US torts. This may not work for GPs but could work well for specialists.
As Obamacare destroys the greatest health care system in the world, that greatness will move to other areas of the world. For Americans of means, health care vacations to foreign destinations will become a reality, just as it currently is for Brits & Canadians now.
Those places have for several years been busily changing their tax and visa rules in order to attract American doctors to set up off shore clinics and practices.
