Slightly confuzzled by the question. It seems like a question you would ask an America hater which I'm not at all. I see plenty of pros to living in America as well as a few cons to living in Canada. I consider America to be a great country. Don't lump me in with betplom.
Maybe I am just imagining those undertones.
As far as the actual question, I just see it as a question of how much it would cost to uproot me. I suppose it would cost a bit more to send me to the States than getting me to move to, say, Vancouver, but nothing crazy. I would love to go somewhere with warmer weather year-round and the States have a few options on that.
There are bunch of points of clarification to this but without over-analyzing, if someone plunked $200K in front of me right now, I would do it.
