First choice would be Paris.
Second would be Fredericton, New Brunswick.
I’m for London, Madame P. wants Paris. So, Paris, obviously.
Belize, English is the official language, has a legal and government system based on the British model (I’m American) and is an open economy.
Southern France . . . probably either Nice, Montpelier or Grenoble. Definitely not Cannes.
I’ve heard good things about both Chile and Belize. In Belize, I speak the language (English); in Chile, I speak enough of the language that after a few months of immersion I’d have it nailed (I think).
Excellent observation. Give it a year or two and Baja California would be the new California… except it’s already…well…uh, you know what I mean. Give it five years and I think we could declare independence and have one seriously lovely little country.
Otherwise, New Zealand and Australia would be my top two choices.
I’d probably pick Ireland. I asked my husband what he thought (he’s sitting in the same room as me) and said, “Don’t ask me stupid questions - I’m watching Bonanza. Shh.” So I’m not gonna let him come with! 
My Beloved says England, but I need a warmer clime, like Brazil.
When you say “free transportation” can I whine that into an ocean capable boat*, forever? If so I’ll just be a homeless wanderer traveling the Earth for the rest of my days.
*It better have satellite internet though.
Ireland was the first place i thought of. I have relatives there, and my late wife’s father was born there. (Which made her an Irish citizen, something we occasionally talked about getting formalized in case we ever decided to move there after I retired.)
Okay, assuming like others that I’m being kicked out of my home country (Canada) I’m going for improving my climate. I’m assuming I’ll be able to support myself wherever I am so cost of living and job availability are not in my factors to be considered.
First choice is probably the US, either Hawaii, Nevada, Arizona or California.
Next would be Belize with 2.5 being a location somewhere in the Caribbean.
Third and final category would be southern Europe. Italy, Greece, Spain, Portugal (all of these would require language acquisition)
My dream vacation has always been to go to España, so I think I would take this opportunity to go there.
My gut answer is Costa Rica. The real answer is that I would wait to see where the rest of the US population went and choose somewhere else! I’m not much for crowds.
whine Do I have to pick one place?
Italy’s food and culture are similar enough to what I’m used to and I know I wouldn’t have problems with the language, but cultural false friends (assumptions that something is the same when it’s not) can be a problem. Plus, well, we share defects as well as vi… I’m not sure we share virtues, but oh boy, do we share defects.
Costa Rica I loved, specially minus the cilantro. Problem is, moving there I’d lose EU citizenship, which is a darn nice thing to have if you’re into working internationally.
I’ve always wanted to learn Greek; sadly, my knowledge of it comes up to half a dozen modern words and several dozen ancient roots. Plus, see above re shared defects.
France is full of French, which is a defect, but then, they’re used to making fun of their southern neighbors and of us making fun of them. Guess I could just move half an hour north to St Jean de Luz, then (I suspect the whole French Basque Country would get an invasion of Spanish Basque anyway; while it’s not my case, many people have family on both sides of the border). And to anybody who minds that I can’t pronunce their R to save my life, pbbbbbbth!
Belize.
No-you’ve got to become a citizen of another already established country…and for trying to work the system, you are travelling by Greyhound and Carnival Cruise Lines.
Czarcasm, if he’s relegated to Carnival Cruise Lines, he WILL be a homeless wanderer for the rest of his days.
Yep-just trying to be fair. 
Can I wait and see where everybody else is going before choosing?
England might be may preferred location but if 150 million Americans are about to move in, I’ll choose elsewhere.
But I’d probably pick Japan. My wife speaks the language so adjustment would be easier, it’ll be less popular as a choice and the infrastructure is modern.
An interesting follow up question would be where would you go if you couldn’t move to a country where they spoke your native language.
