I can’t see a country of old timers moving around the world to get health care.
If one spouse goes, the other will have to go.
Who has that kind of money as a retiree?
Will the Feds provide funds for airfare & room and board ?
ain’t happening.
A lot of people who are retirement age purposely travel as part of their life’s goals; good and more affordable healthcare is a bonus.
Major surgery overseas can cost significantly less, including airfare and hotel, than here in the states.
A secondary benefit is that it will "light a fire" under the AMA monopoly and the Insurance and Tort lawyer cartels.
(of course, that may be precisely why it will not get past Congress even though it would save a ton of money!)
Competition is good!
There are lots of people who do this right now, but for dental work, which of course, isn’t covered by Medicare. In good free enterprise form, Mexican dental clinics have set up right across the border, and many offer hotel stays as well. The cost is so ridiculously less that the difference between what the government would pay and what the patient would pay would cover more than the costs of going abroad and the patient would even have money left over to spend how he or she pleases. Everyone wins.
The feds don’t have to provide funds for airfare, room and board, etc., or anything else. Free enterprise will take care of that. All they need to do is to write the voucher.
