Panama used to be the ex-pat destination until Noriega blew up. There is always going to be something. Belize is nice but it’s already been discovered.
I’ve heard good things about Costa Rica. The real question is whether they allow you to have guns.
Panama has been more stable post Noriega than the US has. Panama has gotten better since say 1992 - you can hardly say the same for the US. In just a couple of decades, the American dream has been badly injured, the soeverignty of our nation and our dollar are both far more shaky, health care is getting ready to tank big time.
The big thing to understand is that people thinking about ex patriating are doing so because they are convinced that America is moving in the wrong direction, and other places are moving in the right direction. There are places that so badly want ex pats that they are offering them a low cost lifestyle and just leaving them alone.
Can you really say that we have a government that’s going to leave us alone for the next 10-20-30 years? The answer is no. If the answer was yes, few would even be interested in this.
