I'm not quite sure if it outweighs the negatives (I wouldn't be looking to move otherwise), and none of it is really unique I don't think but a few things like:
Literally the entire family of my wife and myself are here.
Freedom - I've tried explaining this 5 times now, finding it difficult but we have way more freedom here (which is obviously a double edged sword). But perhaps one example - I can wander around on my bike in the country side and the worst that'll happen is a farmer asks me to turn around rather (happened twice, and only because the road ahead was flooded/blocked). Many European countries 1) don't really have "unexplored" parts 2) Won't allow you to be on those paths anyway. On a related side note petrol is cheaper here too vs Europe.
The weather, I think we are in a pretty good spot, but granted there are places that are similar. None that apply to me though in terms of jobs. Like Australia or NZ are cool places from what I've heard (minus the people in Oz

) but I'll be extremely hard pressed to find work there
Everything seems close, the sea, mountains, forests, anything. But if you're not the outdoor type of course that is a null point. I think (season depending) Europe is similar, the USA it depends where you're based (parts of the north are mind numbingly flat and boring).
And a whole stack of other things that I can't think of right now...
I refer to Europe (or Germany in particular) and USA because those are my main options because of the industry I'm in. So the above statements are more relevant
to me and everyones mileage will vary. Germany I'd not like having half as many sunny days and the unending bureaucracy, whereas I dislike the health, politics and education systems in the USA, etc etc
