Yes, they are partially ideological- but also partially based on actual preferences. I like to snoop around the 'dirty laundry' of various governments (especially my own) when I can, I like to appear right wing (hence I can say to my friends I moved on principle), and I place a very high utility on not having the trauma of going to jail (judging from past experience there's a risk I'd kill a burgular), plus a degree of pride in actually having something resembling actual property rights.
EDIT: In addition, in old age I want to live in something as close as possible to a proper democracy that actually follows the ideals democracy is supposed to. Lack of internet censorship makes for de facto freedom of speech, property rights are self-explanatory (western society says people own their properties, but have a lot of implicit 'but' clauses), and laws forcing me to intervene in a crisis get rid of my liberty. These are trends that are likely to get worse, not better, over time- the trend in the U.S is towards Guantanamo Bay and increased presidential power, Australia has internet censorship and could go further, and Europe has 'intervene in a crisis' laws (the UK as far as I know takes the lead with public security cameras). EDIT TWO: I agree that I should rule out countries I can't get into even with dogged persistence, being Western middle class, and advice from hiring a lawyer. Other than that, I don't see how immigration comes into it.
EDIT: In addition, in old age...
If/when you get to old age, you can move again. Your priorities WILL shift A LOT over the course of a few decades. E.g. freezing weather is an annoyance when you're young, but a mortal handicap when you're old.
My general knowledge and geography is, however, rather poor. There are a few things I want to know about- some general questions, and some things that require at least some rationality to assess.
What I want to avoid:
-Internet censorship
-Laws restricting my ability to 'go about my buisness' (e.g laws in Europe involving intervening in a crisis)
-Weak economies
-Weak property rights (I'd count everywhere where it's illegal to kill a burgular robbing my home- weak meaning weak relative to what I want, admittedly)
-Places of poor employment for whatever profession I go (most likely lawyers).
It's easy to work out where those are the case now- but gaining a decent model of where a country that's nice to live in may exist in the future (i.e no censorship, strong economy, good employment and wages, little interference in my life) is very, very difficult even in the best case scenario. Furthurmore, it's almost certain I can't secure them all.
Does anybody know of any countries where it is likely that over the next two decades or so these standards are at least likely to be well met? I know it's unlikely, but the expected value of posting this is positive and I place a high enough value on finding out that I'm giving it a try.
