Sorry I missed your other part of your post.
Most people I know gravitate towards where the riches are. I know form living here many foriegers come here, make their money, reite and get a Social Security check, then live like Kings of US dollar exchange rate. A lot of Cadian will keep dual citizen ships to keep free health care and Cadian benefits and make their money.
In 1988 a non black market exchange was in Poland 1000 zloty to 1 US dollar. Even though a zloty was not worth much, It was a lot for the ne us dollar. PLus you can't go into a pewex store with currentcy of the country you live in tobuy forien goods.
In work, I had a freind who immagratedfrom Brazil. He cited cutual differnces byut he and his whole family live here for the economic opputunites tehy wold not get in Brazil.
