You will go back to The USA on your knees over the ocean... :)
There are lots of places across the ocean. In some, people would not even consider moving to the US. For them it's good to fly to NYC for a weekend shopping trip (you can get decent jeans for just $50), but that's about it.
Also, no need to go across the ocean for quality living. I had some contracts in the US. Work and money was great but I never felt at home as much as I did in Canada. It was a great feeling to be greeted with "welcome home" at the Canadian border, as opposed to "how much cash are you carrying" at the US one.
The US wasn't it for me, and it isn't it for many. After all life's not just about gas cheaper than a cup of Starbuck's coffee. (btw. wasn't it a Starbucks joint where they charged rescuers on 9/11 for a few pints of hot water?)
