This is a very non-trivial process so your casual response is a bit hard to swallow. And "domino effect" - I don't think there will be a vast tide of of people, but whatever. >> 2) Language barriers

get across non-verbally
So your answer here is great if you are a long-time tourist. Completely impractical in terms of career and work. >> 3) A lot of us have family support systems
that aren't easy to give up
>Yeah, I understand completely ;-)...
No. I don't think you do. I don't think you have a clue. Your family history aside things are much complicated now.For example, its hard enough finding a good school in my own neighborhood (US, english speaking) let along transferring my kids to a new school where they don't speak the language and I have to deal with bureaucracy and hope I'm not screwing up their future. Thats just one quick simple example. Tell a 5 year old she'll never see her friends again and good luck learning French, German, Spanish, or whatever.
I really can't believe you replied with "Yeah, I understand completely ;-)..." to that. Seriously.
On a final note. I'm Irish and lived (US) here 12 years. My family and I can move to Ireland at any time without worry for some of the larger barriers; visa and language.
However to do so is by no means: "extremely simple" or even just "simple".
This is HN, you just left a comment, and not expected to write a thesis on the subject.
That not your fault, people white-wash what are complicated situations all the time and over-simplify. However your off the cuff glib advice is not particular accurate or helpful.
Think before you type. Please.
