I've heard this from a number of people in recent days, as we were leading up to the decision about the ACA and after.
And I very helpfully compiled a list of places these people could go to if that's truly what they want.
I know, most have been talking about Canada, but that's not a viable option for them. For starters, Canada has a universal health care system. And added negative for these people is that they'd have to learn at least some French and given that they hate the French so much they changed the name of French Fries to "Freedom Fries", I doubt that would go over too well.
Mexico doesn't currently have a universal health care, but they are working on one and are closer than we are in the US. I doubt they could overcome their extreme hatred of Mexicans to immigrate there. I wonder, though, if they'd be comfortable in other places in South America? They could at least still call themselves "Americans" if they took up permanent residence in Peru, Paraguay, Bolivia, or Ecuador, the countries without universal health care.
Almost all of Africa is wide open as far as alack of universal health care. South Africa is trying to get something together but the rest of the country seems to be just the wild and free sort of place they claim to crave. A bit lacking in technological amenities, but I'm sure they won't mind that when they are comfortably ensconced in Rwanda without any pesky universal health care annoying them. I can only find immigration information on South Africa, but surely a determined person desiring to abandon the US can find what they need?
The following countries aren't big on immigration, but between visas and green cards, they might be able to stay on in them for a long time: China, Turkey, Thailand, Vietnam (no sites I can find in English), Papua New Guinea, Madagascar.
I give these lists to people who whine to me that they need to get out of the US because of the ACA. It causes them to pause because most of them don't even know where these countries are (granted, Africa is a continent and not a country, but almost all the countries there lack the dreaded universal health care).
They either glare angrily at me with their mouths flapping like an out-of-water fish or they clamp their mouths tightly shut and leave, sometimes after a huffy, "Well, I never!"
I just want to be helpful. I guess, if they can't abide the ACA, they really can't abide someone helping them altruistically.
"Altruistically" isn't part of their vocabulary.
