America.
No really - I've never trusted the country, the majority of the people seem nice enough but the crime rate... the justice system... the healthcare, the country itself is insane.
If I went there and got mugged but also stabbed, knowing my luck I'd go to hospital to have a life-saving 40 grand operation I can't afford, then I'd become bankrupt and it turns out the mugger is pushing harassment charges for trying to yell for help and saying nasty things about him later.
I won't go into my other views, considering I've never been there and never plan to. But I've heard enough from friends who moved over here from America and pen-pals to know that really, even a More Economically developed country can still be utterly terrible, corrupt and really - just hell in a lot of places which aren't profitable enough.
